The Battery Component Readiness Level (BC-RL) framework: A technology-specific development framework

Government investment constitutes a large portion of overall investment in research and development of lithium-ion batteries (LIBs) and other future battery technologies with the goal of electrifying the transportation sector and so removing a major source of global greenhouse gas emissions. Poor investments, however, can result in taxpayer funding losses and political backlash, making clear communication and informed decision-making critical. This manuscript presents the Battery Component Readiness Level scale, an overhauled version of the Technology Readiness Level (TRL) scale currently utilized by the EU for innovation programs that has been customized for use in battery technology development. It retains the structure of the EU TRL scale while adding in-depth description of technology-specific development as well as discussion of aspects such as manufacturability and cost that are necessary to understand technological promise and risk. Its use by the EU and other parties involved in battery development can thus improve communication between all involved sectors, from government to academia to industry, and can aid in better-informed decision-making regarding investments. This can ultimately contribute to a more efficient electrification of the transportation sector and any other sectors where batteries display transformative potential.

Lithium substituted poly(amic acid) as a water-soluble anode binder for high-temperature pre-lithiation

Multifunctional binders hold great promise in advanced electrode designs for both fundamental research and practical utilization of lithium-ion batteries (LIBs). The reactions between Si/SiO x -dominated anodes with lithium are expected to be exothermic in principle, while the thermal tolerance along with the volume change makes high-temperature binders attractive for large scale roll-to-roll manufacturing. For instance, if a high temperature binder is also water soluble, it can be compatible with the current graphite-based anode manufacturing process. In this work, we present a water-soluble poly(amic acid)-based binder, which can withstand high temperature for industrial pre-lithiation process and effectively hold active materials together during repeated charge and discharge cycles. This lithium substituted poly(amic acid) binder (denoted as Li-Pa) can serve as a drop-in replacement for environmentally friendly electrode fabrication in large scale by providing aqueous solubility, exceptional thermal stability and mechanical flexibility. • A water-soluble lithium substituted poly(amic acid) binder was designed for Si electrodes. • Thermal imidization of lithium substituted poly(amic acid) to polyimide was achieved. • Polyimide binder based Si electrodes are thermally stable up to 500 °C. • High temperature pre-lithiation can be performed on these electrodes.

High Nickel and No Cobalt─The Pursuit of Next-Generation Layered Oxide Cathodes.

The prosperity of the electric vehicle industry is driving the research and development of lithium-ion batteries. As one of the core components in the entire battery system, cathode materials are currently facing major challenges in pushing a higher capacity up to the materials' theoretical limits and transitioning away from unaffordable metals. The search for next-generation cathode materials has shifted to high-nickel and cobalt-free cathodes to meet these requirements. In this review, we distinctly point out the shortcomings of cobalt in stabilizing layered structures and systematically summarize the recent efforts to eliminate cobalt and achieve higher nickel content in layered cathode materials. Finally, a reasonable prospect is put forward for further development of layered cathode materials and other promising candidates, which is likely to spur a wave of efforts toward developing high-performance and low-cost Li-ion batteries.

Investigation on Structural and Electrochemical Properties of Olivine-Structured LiMn1−xFexPO4/C Cathode Materials Based on First-Principles Calculation

Currently, LiMnPO4 is a highly prevalent cathode material in lithium-ion batteries. However, its low conductivity and Li+ diffusion rate limit its practical application. To overcome these inherent defect, we have modified its properties by doping Fe at the Mn site. In the LiMn1-xFexPO4 system, the total density of states of electrons near the Fermi level and the energy band of the Fermi surface are obtained by first-principles calculation. The adjustment of the energy band width immediately influences the electronic conductivity of LiMn1-xFexPO4 system, which is positively related to the electrochemical performance. According to the results of first-principles calculation, we speculated that x = 1/4 was the optimal doping concentration. Then, the LiMn1-xFexPO4/C systems were compounded by hydrothermal method to verify the first-principles’ hypothesis. The electrochemical tests show that the LiMn3/4Fe1/4PO4/C material has the best cycle performance and rate performance. At the condition of 0.05 C rate, this material possesses an initial discharge capacity of 142.5 mAh g−1. with the capacity retention maintained 93.9% after 100 cycles. The theoretical calculation in consistent with the experimental findings, which accounts for the fact that the first-principles strategy is very effective in the research and development of lithium-ion batteries.

Analysis of the performance decline discipline of lithium-ion power battery

Prediction of state of health (SOH) of lithium-ion batteries can extend the service life of the batteries and improve the safe performance of the batteries, which is of great significance to research and development of lithium-ion batteries. Aiming at the problems that the discharge current of electric vehicles constantly changes under actual operating conditions and the number of full charge-discharge cycles is small, a battery health prediction model based on capacity decay rate is proposed. In this paper, the ternary cathode material power lithium-ion battery with a rated capacity of 5Ah is taken as the research subject, and the discharge experiment is conducted under the conditions of ambient temperature of 0 °C, 10 °C, 20 °C, 30 °C, and 40 °C. By fitting the curve of the battery capacity with the number of cycles, the decay rate of the battery capacity with the number of cycles is obtained.

The Hazards Analysis of Nickel-Rich Lithium-Ion Battery Thermal Runaway under Different States of Charge

The lithium-ion battery industry has been developing rapidly, with energy density and capacity constantly improving. However, the ensuing safety accidents of lithium-ion power batteries have seriously threatened the personal safety of passengers. Therefore, more and more attention has been paid to the thermal safety research of lithium-ion batteries, such as thermal runaway (TR) mechanism analysis and prevention methods, etc. In this paper, the nickel-rich 18650 lithium-ion batteries with Li[Ni0.8Co0.1Mn0.1]O2 cathode in different states of charge (SOC) are taken to investigate the TR characteristics using an extended volume plus acceleration calorimeter (EV+-ARC). In order to evaluate the TR characteristics, some characteristic parameters such as battery voltage, surface temperature, temperature rise rate, etc. are selected from the experiment to analyze the influence of SOC on the critical state of TR. It can be seen from the experiment results that the maximum temperature of the battery surface decreases with the decrease of SOC, while the self-generated heat temperature and TR trigger temperature increases with the decrease of SOC.

Incentivizing Innovation: The Causal Role of Government Subsidies on Lithium-Ion Battery Research and Development

Governments design and implement policies to achieve a variety of goals, but perhaps none are as pressing as shifting national economies away from non-renewable fuels and towards more sustainable, environmentally-friendly technologies. To incentivize such transitions, governments provide subsidies to private and public companies to innovate, i.e., to engage in research and development (R&D) to develop those technologies. However, the question of the companies is using government subsidies (GS) to perform R&D and its answer determines the effectiveness of government policies. Consequently, this paper seeks to answer this question through investigating Chinese lithium-ion battery (LiB) firms and the GS they receive through novel usage of information flow (IF). Hausman tests, fixed- and random-effects models confirmed a weak, though positive correlation between GS and R&D as determined by patent output (PO), but interestingly, observations of IF intimated that GS also affected other variables such as net profit (NP) and main business income (MBI). This suggests that firms are being awarded GS for higher PO, but a corresponding increase in R&D and its expected growth in company performance is not occurring. Thus, it is suggested that performance variables other than PO be used as firms may ab (use) this metric to apply for more GS, rather than performing R&D that leads to technological breakthroughs.

ZnSe/CoSe/NCDPH composites as anode materials for lithium ion batteries with high capacity and long cycle

In this paper, dopamine hydrochloride (DPH) is introduced to synthesize ZIF-8@ZIF-67@DPH in the preparation of ZIF-8@ZIF-67. ZnSe/CoSe/NCDPH (N-doped carbon) composites are calcined in a high-temperature inert atmosphere with ZIF-8@ZIF-67@DPH as the precursor, selenium powder as the selenium source. ZnSe/CoSe/NCDPH has high discharge specific capacity, good cycle stability and outstanding rate performance. The first discharge capacity of ZnSe/CoSe/NCDPH is 1616.6 mAh g−1 at the current density of 0.1 A g−1, and the reversible capacity remains at 1214.2 mAh g−1 after 100 cycles, the reversible capacity is 416.7 mAh g−1 after 1000 cycles at 1 A g−1. Therefore, ZnSe/CoSe/NCDPH composites provide a new step for the research and synthesis of new stable, high-capacity, and safe high-performance lithium ion batteries. The bimetallic selenide composites not only have bimetallic active sites, but also can form synergistic effect between different metal phases, which can effectively reduce the capacity attenuation caused by volume expansion and reactive stress enrichment during lithium storage of metal oxide anode materials. Meanwhile, N-doped carbon can improve the conductivity and provide more active sites to store lithium, thus improving its lithium storage capacity.

Defect Engineering and Anisotropic Modulation of Ionic Transport in Perovskite Solid Electrolyte LixLa(1-x)/3NbO3.

Solid electrolytes, such as perovskite Li3xLa2/1−xTiO3, LixLa(1−x)/3NbO3 and garnet Li7La3Zr2O12 ceramic oxides, have attracted extensive attention in lithium-ion battery research due to their good chemical stability and the improvability of their ionic conductivity with great potential in solid electrolyte battery applications. These solid oxides eliminate safety issues and cycling instability, which are common challenges in the current commercial lithium-ion batteries based on organic liquid electrolytes. However, in practical applications, structural disorders such as point defects and grain boundaries play a dominating role in the ionic transport of these solid electrolytes, where defect engineering to tailor or improve the ionic conductive property is still seldom reported. Here, we demonstrate a defect engineering approach to alter the ionic conductive channels in LixLa(1−x)/3NbO3 (x = 0.1~0.13) electrolytes based on the rearrangements of La sites through a quenching process. The changes in the occupancy and interstitial defects of La ions lead to anisotropic modulation of ionic conductivity with the increase in quenching temperatures. Our trial in this work on the defect engineering of quenched electrolytes will offer opportunities to optimize ionic conductivity and benefit the solid electrolyte battery applications.

Dualbeam Platform Applications in Lithium Battery Research

Lithium batteries are energy storage systems with highly complex microstructures. To understand the performance of the battery it is essential to accurately characterize the battery microstructure at multiple length scales. However, there are multiple challenges in battery characterization such as beam damage, imaging liquid phases and getting to representative volumes.The DualBeam, also known as focused ion beam–scanning electron microscope (FIB-SEM) technique is an analytical method combining an ion beam for materials processing and an electron column for imaging to enable 2D and 3D characterization at the nanometer scale. In this presentation the application of three different DualBeam techniques for battery characterization and how to handle the imaging challenges are discussed for different sample types.A battery separator is a beam sensitive sample and imaging conditions need to be optimized to avoid damaging the separator morphology. By using cryo techniques in a Ga-based FIBSEM, the cross-section and 3D structure of a separator sample is analyzed. The second example deals with a thick NMC electrode sample. Considering the thickness of the cathode (>70 µm) and the active particle size (~10 µm) particle size, a field of view >100 um is needed to get to a representative volume. The combination of Xe-plasma FIB (PFIB) with Avizo software is used to study the electrode microstructure evolution during cycling to better understand the degradation mechanism. The final example is about accessing the liquid-solid interphase inside of the electron microscope. By using a laser PFIB under cryogenic condition, the interphase of the liquid-solid in a Li-metal battery is explored, which is critical to decipher the root cause for cycling inefficiency.DualBeam technology enables new analytical capabilities for materials research while opening up exciting opportunities for advancing battery development. It is expected to remain an indispensable technique for supporting battery innovation in both academic and industrial environments.

Interpretation and Modelling of the Electrochemical Impedance of LiFePO4/Li4Ti5O12 Batteries

Significant effort has been devoted to the research and development of safe lithium ion batteries in the last three decades. The commercial 26650 LiFePO4/Li4Ti5O12 (LFP/LTO) battery has been specifically found in many applications in which safety and cycle-life are of prime importance. The cell consists of olivine LiFePO4 as cathode, which is one of the most thermally stable, non-toxic, and long-cycle-life cathode materials, and spinel Li4Ti5O12 as anode, which features zero-strain Li intercalation, flat and relatively high operating voltage, and high thermal stability. In order to assess and improve the power capability and stability of these safe and long-life batteries, it is important to investigate and understand performance characteristics of individual cell components and interfaces, in order to elucidate the rate determining processes at each electrode. In this work, electrochemical impedance spectroscopy (EIS) analysis facilitated by distribution of relaxation times (DRT) is used to study the LFP/LTO cell at different states of charge (SOC) and SOC history, and an equivalent circuit model (ECM) is proposed in order to better understand the main processes at the anode and cathode and quantify their contribution to the full cell impedance. The modeling and interpretation of the full cell EIS is complicated because the LFP and LTO responses appear over similar frequency ranges. In order to unambiguously separate the anode and cathode contributions, EIS spectra from LTO/Li and LFP/Li half cells were also measured at different SOC and SOC history and the fit results were used to develop the full-cell ECM. The LFP/LTO cell impedance changes slightly only at low SOCs during charge, whereas it changes significantly during discharge. This SOC history dependence, i.e., the EIS response of a particular SOC depending on the previous SOC (Figure 1a), was mainly attributed to the change in the LFP electrode charge transfer process frequency and resistance (Figure 1b). This variation was found to be minimized at high SOCs and maximized at low SOCs (Figure 1), e.g., the LFP electrode charge transfer resistance in the full cell at 90% SOC was 11.3 Ωcm2 in charge vs 11.4 Ωcm2 in discharge (~1% difference) and at 10% SOC was 9.7 Ωcm2 in charge vs 13.3 Ωcm2 in discharge (~37% difference). As seen in the DRT results (Figure 1b), the frequency of the charge transfer process at the LFP electrode showed the same variation, i.e., it happens at 2.15 Hz at 90% SOC in charge vs 1.73 Hz in discharge (~20% difference) and at 1.31 Hz at 10% SOC in charge vs 0.55 Hz in discharge (~42% difference). The LTO electrode showed relatively little change in the charge transfer resistance and frequency with SOC and SOC history (Figure 1b).Figure 1. EIS response from the full 26650 cell at different SOC during charge (red lines) and discharge (back lines): a) shows the Nyquist plots and b) shows the DRT results. The spectra are shown after the truncation of the negative values of -Zimag and are normalized to the surface area of the electrodes. Figure 1

Dunaliella Salinas based Sn-carbon anode for high-performance Li-ion batteries.

Long life, high capacity, environmental friendliness and good rate performance are the most important elements in the research of lithium ion batteries (LIBs). In this paper, Sn–carbon composite electrode materials are prepared using Dunaliella Salinas based carbon (amorphous carbon) as an amorphous carbon precursor combined with tin. Hence, an amorphous carbon template enwrapped by Sn particles forms a core–shell structure (Sn–carbon composite), the annealed Dunaliella Salinas based carbon makes up the carbon core, and Sn particles form the shell of the material. The components of the materials, microstructure and electrochemical properties of LIBs were characterized and tested. The results show that the prepared Sn–carbon composite electrode materials have high purity and combine with amorphous carbon uniformly. The Sn–carbon composite exhibits excellent performance as a LIB anode, its discharge capacities of the 1st, 2nd, and 4th cycles are 1777.39, 944.15 and 722.46 mA h g−1 at a current density of 100 mA g−1, and the capacity is 619.09 mA h g−1 after stable cycling at a current density of 200 mA g−1. The capacity continues to rise at a high current density of 1000 mA g−1 and is 574.97 mA h g−1 at its maximum, demonstrating the excellent performance of the electrode.

A health indicator extraction based on surface temperature for lithium-ion batteries remaining useful life prediction

For the close relationship with safety, surface temperature has been a hot topic in the research of lithium-ion batteries. Studying surface temperature changes can ensure safety and provide information for degradation estimation. However, there are few studies on obtaining degradation information from surface temperature. In this paper, a new health indicator (HI) is proposed to predict the remaining useful life (RUL) of lithium-ion batteries from the discharge surface temperature, which is convenient for real-time measurement and online estimation. First, according to the actual trend of surface temperature, an exponential model is used to fit the surface temperature from 1000 s to the end of the discharge. Then, a new HI is extracted from the model parameters, which indicates the change rate of surface temperature. Pearson and Spearman correlation analysis verified that HI is related to battery capacity degradation. What's more, a comparison of the new HI and other types of HIs is performed. Finally, a method combining HI and relevance vector machine (RVM) is proposed for online RUL prediction. Predictions have been made for different algorithms and starting points, the results show that the new HI is effective for degradation modeling. And the RUL prediction error is less than 5 cycles for 5#, 6# and 7# batteries.

(Battery Division Postdoctoral Associate Research Award Address Sponsored by MTI Corporation and the Jiang Family Foundation) Extending Battery Life - Studies within the Faraday Institution on NMC811/Graphite Full Cells

To support the rapidly growing adoption of electric vehicles and renewable grid-storage systems, it is desirable to develop lithium-ion batteries with higher energy density and improved rate capability. However, the design of such energy-dense cell chemistries is impeded by a trade-off with cycling and calendar lifetimes. A key goal for the automotive and utilities industries is therefore to better understand the causes and mechanisms of degradation. This will enable improved control and prediction of the state of health of battery systems.As part of the Faraday Institution, the UK’s independent institute for electrochemical energy storage technology, the Battery Degradation Programme is building new understanding of the underlying physical and chemical processes that can lead to degradation in energy-dense NMC811/graphite lithium-ion cells as a model system. Led by the University of Cambridge (Clare Grey PI) in collaboration with 11 UK universities and institutions, the research consortium is working closely with industry partners to create a new hub for lithium-ion battery research and to address key challenges and opportunities in the field. This presentation will give an overview of the research consortium’s membership, key milestones, and technical progress.To date, the consortium has been applying a variety of analytical techniques to study degradation processes in NMC811/graphite cells. For example, electrochemical testing, operando synchrotron X-ray diffraction (XRD) and ex situ solid-state 7Li nuclear magnetic resonance spectroscopy (NMR) were combined to understand how changes in lithium dynamics correlate with the interlayer spacing changes that occur during delithiation.1 The method is now being applied to understand how the dynamics are affected by long-term structural damage to the NMC811 material. New spectroscopic methods are also being developed, including Kerr-gated Raman, which allows sensitive measurements of electrode materials and electrolytes with lower background signal than conventional Raman spectroscopy.2 X-ray computed tomography methods have been developed for in situ and operando studies of particle cracking during charging, cycling, or storage.3 Finally, Gaussian process machine learning is being applied to correlate electrochemical impedance spectral features with degradation patterns and to consider the value of EIS signals in battery management systems.4 Reference s: 1.

Glovebox-integrated XES and XAS station for in situ studies in tender x-ray region

X-ray emission spectroscopy (XES), as a complementary technique to x-ray absorption spectroscopy (XAS), is powerful in the analysis of the electronic structure of the materials by probing the occupied density of states with high energy resolution. Recently, an XES spectrometer optimized for the tender x-ray region (2–5 keV) was successfully installed into an inert atmosphere glovebox, and the entire system was successfully integrated into the SXRMB (soft x-ray microcharacterization beamline) at the Canadian Light Source. Here, the technical design and the performance of the SXRMB XES-integrated glovebox station is presented. High energy resolution of ∼1 eV or better has been achieved for the spectrometer in the tender energy x-ray ranges. Capability of the station for in-situ XES and XAS measurements is demonstrated using an example of phosphorus phase transformation in phosphorus anodes for lithium-ion battery research.

A Pathway to Understand NMC Cathodes

Developing low-cost and high-performance cathode materials is an on-going challenge for lithium-ion battery research. In a recent issue of Cell Reports Physical Science, Finegan and coworkers present electron backscatter diffraction as a technique to provide new insights into grains, grain boundaries, and morphologies of LiNixMnyCozO2 cathode materials.

(Invited) Enhancing Oxygen Stability in High-Nickel Cobalt-Free Layered Oxide Cathode Materials By Three-Dimensional Targeted Doping

The price of cobalt, a key element within lithium-ion batteries (LIB) for stability, has nearly tripled over the past few years due to increased demand from the cell phone industry, a current materials shortage, and speculation for a future global shortage. Given the increase in cost and the future outlook, lithium-ion battery (LIB) research focused on the reduction or the elimination of cobalt within a LIB is essential for reducing the cost and assuring the supply of lithium-ion batteries. This talk will report on the development a novel three-dimensional (3D) doping approach that is poised to resolve some longstanding challenges in fundamental doping effects on high-Ni Co-free battery materials as well as to reduce the cost and improve the safety, energy density, and lifetime of LIBs.

Methods of Composite Electrode Imaging

Lithium intercalation electrodes are composite devices that consist of typically at least four different constituents that provide separately charge storage, electronic conduction, ionic conduction and mechanical integrity. Consequently, the microstructure of these composites has an important role to play in intercalation electrode performance. An inhomogeneous electrode microstructure affects battery performance by increasing peak local current densities and resistances during the operation. This reduces accessible capacity, compromises safety, as it facilitates localized overcharging, and impacts ion transport and consequently power performance.1 Origins for inhomogeneity in electrode microstructure can lie in the casting procedure, slow carbon agglomeration over cycling as well as in binder adhesive failure due to active material volume changes, which causes a connectivity loss between active material and the matrix.Given this impact of the electrode microstructure, an improved understanding of microstructure and microscopic performance variations is of great importance to optimizing overall battery performance. As such, we need tools that allow us to measure microscopic performance, and correlate to microstructure, interfaces and their development over cycling. Thus a variety of spatial imaging techniques can be used to characterize the processes ex situ, in situ, and operando. Each technique gives a unique and specific information about certain process.2 , 1 We are highlighting herein X-ray tomography and scanning electrochemical microscopy (SECM) as tools for the investigation of disconnection mechanisms.X-ray Tomography (XRT) is a 3D imaging technique used to visualize complex mechanical interactions in batteries during operation. This nondestructive technique can provide a spatial resolution down to the nanometer scale. X-ray tomography can provide information of the material porosity and tortuosity, chemical composition and crystals and the reactions inside the battery.4 , 2 We are using this technique in the imaging, analysis and tracking of electrode microstructure with cycling.Scanning electrochemical microscopy (SECM) is a scanning probe technique that uses a microscopic electrochemical electrode as probe. This allows the measurement of local electrochemical activity on a substrate surface. It has previously been used to investigate the properties of solid electrolyte interphase (SEI) of the negative electrode as well as exploring the lithium ion activity at micro and nano scales resolution.3 We are employing this method to correlate microstructure and performance inhomogeneity.This presentation summarizes first results from both techniques and contrasts structural with performance inhomogeneity. We will be using these tools as we are developing new binders and microstructures for intercalation electrodes to improve the synergy between electrode constituents and optimize overall electrode performance.References(1) Müller, S.; Eller, J.; Ebner, M.; Burns, C.; Dahn, J.; Wood, V.

Effect of Combined Conductive Polymer Binder on the Electrochemical Performance of Electrode Materials for Lithium-Ion Batteries

The electrodes of lithium-ion batteries (LIBs) are multicomponent systems and their electrochemical properties are influenced by each component, therefore the composition of electrodes should be properly balanced. At the beginning of lithium-ion battery research, most attention was paid to the nature, size, and morphology peculiarities of inorganic active components as the main components which determine the functional properties of electrode materials. Over the past decade, considerable attention has been paid to development of new binders, as the binders have shown great effect on the electrochemical performance of electrodes in LIBs. The study of new conductive binders, in particular water-based binders with enhanced electronic and ionic conductivity, has become a trend in the development of new electrode materials, especially the conversion/alloying-type anodes. This mini-review provides a summary on the progress of current research of the effects of binders on the electrochemical properties of intercalation electrodes, with particular attention to the mechanisms of binder effects. The comparative analysis of effects of three different binders (PEDOT:PSS/CMC, CMC, and PVDF) for a number of oxide-based and phosphate-based positive and negative electrodes for lithium-ion batteries was performed based on literature and our own published research data. It reveals that the combined PEDOT:PSS/CMC binder can be considered as a versatile component of lithium-ion battery electrode materials (for both positive and negative electrodes), effective in the wide range of electrode potentials.
