Facile one-step fabrication of Li4Ti5O12 coatings by suspension plasma spraying

Spinel Li4Ti5O12 (LTO) is a promising anode material for solid state thin film batteries (SSTB) due to its almost-zero volume change and promising Li-ion mobility. However, preparing LTO anodes for SSTB demands tedious vacuum-based processing steps that are not cost effective. In this context, the present study embarks on evaluating the versatile suspension plasma spraying (SPS) approach to fabricate LTO coatings without using any binder. The microstructure and stoichiometry of the fabricated LTO coatings developed through the SPS route reveals retention of ∼76 wt.% of the spinel LTO from the starting feedstock, with minor amounts of rutile and anatase TiO2. The SPS experiments yielded varying thickness build up rates of the LTO coatings depending on the processing parameters adopted. The electrochemical data of the produced LTO based electrode tested in a half-cell through galvanostatic cycling show reversible lithiation and delithiation at expected potential, thereby validating the promise of the SPS technique for potential fabrication of SSTB components once fully optimized.

Deciphering the structural and kinetic factors in lithium titanate for enhanced performance in Li+/Na+ dual-cation electrolyte

The widespread application of Li4Ti5O12 (LTO) anode in lithium-ion batteries has been hindered by its relatively low energy density. In this study, we investigated the capacity enhancement mechanism of LTO anode through the incorporation of Na+ cations in an Li+-based electrolyte (dual-cation electrolyte). LTO thin film electrodes were prepared as conductive additive-free and binder-free model electrodes. Electrochemical performance assessments revealed that the dual-cation electrolyte boosts the reversible capacity of the LTO thin film electrode, attributable to the additional pseudocapacitance and intercalation of Na+ into the LTO lattice. Operando Raman spectroscopy validated the insertion of Li+/Na+ cations into the LTO thin film electrode, and the cation migration kinetics were confirmed by ab initio molecular dynamic (AIMD) simulation and electrochemical impedance spectroscopy, which revealed that the incorporation of Na+ reduces the activation energy of cation diffusion within the LTO lattice and improves the rate performance of LTO thin film electrodes in the dual-cation electrolyte. Furthermore, the interfacial charge transfer resistance in the dual-cation electrolyte, associated with ion de-solvation processes and traversal of the cations in the solid-electrolyte interphase (SEI) layer, are evaluated using the distribution of relaxation time, Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. Our approach of performance enhancement using dual-cation electrolytes can be extrapolated to other battery electrodes with sodium/lithium storage capabilities, presenting a novel avenue for the performance enhancement of lithium/sodium-ion batteries.

High Performance Ti3+ Self-Doped Li4Ti5O12 Anode Materials Synthesized by an Electrochemical Method in Molten Salt

A simple synthesis for the Ti3+-doped, small Li4Ti5O12 is favorable for its application as an anode material of lithium-ion batteries. This study presents a direct synthesis method of high-performance Li4Ti5O12 (LTO-Ti) with the Ti3+ self-doped and uniformly small in size. It is carried out by the redox of an electrochemical electrode pair of Ti and Fe2O3 at a constant potential in molten KCl-LiCl salt with Li2CO3. The synthesis mechanism and the effect of synthesis conditions on the formation and properties of LTO-Ti were investigated in detail. The LTO-Ti with an average size of approximately 400 nm is prepared by the ionic level synthesis method, and exhibits a superior specific capacity of 130.5 mAh·g−1 at 10 C current density, which is 73.6% of its average specific capacity at 1 C. Moreover, it also shows good cycling stability with a specific capacity of 127.2 mAh·g−1 after 1000 cycles at 5 C (capacity retention of 96.9%). This synthesis is secure and prospective.

Continuum insight into the effects of electrode design parameters on the electrochemical performance of lithium-ion batteries

Lithium-ion batteries energy and power density strongly depend on the type of active material and the electrode design parameters. An in-depth understanding of the effect of battery design parameters on their electrochemical performance is experimentally expensive and hence requires the utilization of cheaper continuum scale models. Here, using a lithium-ion cell composed of LiFePO4 cathode, Li4Ti5O12 anode and a porous separator filled with a liquid electrolyte as an example, we demonstrate the use of an experimentally validated pseudo-two-dimensional (P2D) model in one-dimension to explore the effects of different cell design parameters on the discharge capacity at different current rates. The model is simulated in two-dimensional to instantly visualize the concentration distribution of Li ions in the electrode at high discharge current rates. The continuum model unravels that the solution phase diffusion limitation is the main factor inhibiting the performance of thick electrodes at high current rates and the Li4Ti5O12 anode is the limiting electrode. These findings using continuum models provide guidance for and accelerate the optimization of electrode architecture for enhancing the performance of lithium-ion batteries.

Freeze-drying synthesis of metal element (Zr, Cr, Co)–doped Li4Ti5O12 anode material for enhanced electrochemical energy storage in lithium-ion batteries

Metal-Doped NASICON/Polymer Composite Solid Electrolyte for Lithium Titania Anode in Lithium-Ion Batteries.

This study reports five types of metal-doped (Co, Cu, Sn, V, and Zr) NASICON-type Li1.3Al0.3Ti1.7(PO4)3 (LATP)/polymer composite solid electrolytes (CSEs) enabling Li4Ti5O12 (LTO) anodes to have high rate capability and excellent cycling performance. The high Li+-conductivity LATP samples are successfully synthesized through a modified sol-gel method followed by thermal calcination. We find that the cation dopants clearly influence the substitution of Al for Ti, with the type of dopant serving as a crucial factor in determining the ionic conductivity and interfacial resistance of the solid electrolyte. The CSE containing poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP), lithium bis(trifluoromethanesulfonyl)imide (LiTFSI), and Sn-LATP shows an ionic conductivity of 1.88 × 10-4 S cm-1 at ambient temperature. The optimum conductivity can be attributed to alterations in the lattice parameters and Li+ transport pathways owing to Sn doping. The solid-state cell equipped with the LTO-supported CSE containing Sn-LATP fillers demonstrates both excellent high rate capability at 5 C (with a capacity retention of 86% compared to the value measured at 0.2 C) and superior cycling stability, maintaining high Coulombic efficiency (>99.0%) over 510 cycles. These findings indicate that the proposed CSE is highly promising for use in solid-state lithium batteries with desirable charge-discharge properties and high durability.

Functional AlF3 modification over 5 V spinel LiCoMnO4 cathode for Li-ion batteries

We report the improved electrochemical activity of the 5 V LiCoMnO4 (LCMO) cathode with the functionalization of AlF3 coating. LCMO@AlF3 is prepared by adopting the co-precipitation technique followed by a wet coating by altering the concentration of AlF3 by 1–3 wt.%. LCMO@AlF3 exhibits improvement in the electrochemical performance compared to pristine LCMO. In addition, LCMO@AlF3 exhibits superior electrochemical performance with specific capacities of 107, 102, and 95 mAh g−1 and retentions of 68, 77, and 74% after 100 cycles for 1, 2, and 3 wt.% AlF3 coating. However, pristine LCMO shows a specific capacity of 105 mAh g−1 with a retention of 48% after 100 cycles. Also, LCMO@AlF3 exhibits a decrement in the irreversible capacity loss (ICL) compared to pristine LCMO, which enhances the coulombic efficiency of the former compared to the latter. Further, the AlF3 coating of 2 and 3 wt.% has been optimized to exhibit excellent electrochemical performance. The diffusion coefficients are calculated from cyclic voltammetric and electrochemical impedance spectroscopic techniques and are in the order of ∼10−12 cm2 s−1. Further, in-operando and in-situ impedance studies are conducted to authenticate the electrochemical activity observed in half-cell studies. In full-cell assembly with Li4Ti5O12 (LTO) anode, the LCMO@AlF3: 2–3 wt.% exhibits better electrochemical performance compared to its bare configuration. In addition, the electrochemical activity at various temperature (−10 to 25 °C) conditions is performed and reported.

Fabrication of Li4Ti5O12 (LTO) as Anode Material for Li-Ion Batteries.

The most popular anode material in commercial Li-ion batteries is still graphite. However, its low intercalation potential is close to that of lithium, which results in the dendritic growth of lithium at its surface, and the formation of a passivation film that limits the rate capability and may result in safety hazards. High-performance anodes are thus needed. In this context, lithium titanite oxide (LTO) has attracted attention as this anode material has important advantages. Due to its higher lithium intercalation potential (1.55 V vs. Li+/Li), the dendritic deposition of lithium is avoided, and the safety is increased. In addition, LTO is a zero-strain material, as the volume change upon lithiation-delithiation is negligible, which increases the cycle life of the battery. Finally, the diffusion coefficient of Li+ in LTO (2 × 10-8 cm2 s-1) is larger than in graphite, which, added to the fact that the dendritic effect is avoided, increases importantly the rate capability. The LTO anode has two drawbacks. The energy density of the cells equipped with LTO anode is lower compared with the same cells with graphite anode, because the capacity of LTO is limited to 175 mAh g-1, and because of the higher redox potential. The main drawback, however, is the low electrical conductivity (10-13 S cm-1) and ionic conductivity (10-13-10-9 cm2 s-1). Different strategies have been used to address this drawback: nano-structuration of LTO to reduce the path of Li+ ions and electrons inside LTO, ion doping, and incorporation of conductive nanomaterials. The synthesis of LTO with the appropriate structure and the optimized doping and the synthesis of composites incorporating conductive materials is thus the key to achieving high-rate capability. That is why a variety of synthesis recipes have been published on the LTO-based anodes. The progress in the synthesis of LTO-based anodes in recent years is such that LTO is now considered a substitute for graphite in lithium-ion batteries for many applications, including electric cars and energy storage to solve intermittence problems of wind mills and photovoltaic plants. In this review, we examine the different techniques performed to fabricate LTO nanostructures. Details of the synthesis recipes and their relation to electrochemical performance are reported, allowing the extraction of the most powerful synthesis processes in relation to the recent experimental results.

Metal sulfides encapsulated in doped carbon aerogel towards superior and safe energy storage: Two birds with one stone

Up to now, lithium/sodium ion batteries (LIBs/SIBs) are deemed as the ideal candidates for traditional fossil energy. However, the absence of suitable Li+/Na+ reservoirs and the hazard of thermal runway have plagued their usages. Using Li4Ti5O12 or TiO2 anode promotes the thermal safety of LIBs/SIBs but reduce their electrochemical property. How to achieve the balanced performances has been an urgency. Here, we have delicately designed a 3D micro-nanostructure of CoS2/doped carbon aerogel (CoS2@NCA), via “killing two birds with one stone” strategy. When used as LIBs anode, CoS2@NCA delivers a high capacity of 639.5 mAh g−1 after operating at 1 A g−1 for 250 cycles, giving a low-capacity attenuation rate of 0.048 % per cycle. Meanwhile, the reduced maximum temperature and maximum heating rate of thermal runaway (TR) are observed for cell. When used as SIBs anode, CoS2@NCA delivers a high capacity of 620.9 mAh g−1 at 100th cycle as working at 1 A g−1. Likewise, the activation energy for TR is promoted. Overall, the utilization of CoS2@NCA enables the superior and safe energy storage.

High-power recycling: upcycling to the next generation of high-power anodes for Li-ion battery applications

Upcycling current high power electrodes (Li4Ti5O12) towards the next generation of titanium niobium oxide materials, while reclaiming a critical element: lithium.

Failure mechanisms of the Li(Ni0.6Co0.2Mn0.2)O2-Li4Ti5O12 lithium-ion batteries in long-time high-rate cycle.

With the ever-growing widespread use of lithium-ion batteries in heavy machinery and daily life, the demand for improved longevity and high-rate performance is escalating. While Li4Ti5O12 (LTO) batteries excel in safety and cycling performance, their full potential for long-term, high-rate cycling still yet remains unrealized. In this paper, we present an analysis of a pouch battery with an LTO anode system that was cycled for an extended period at high rates. We compared the performance changes and internal component properties between fresh and cycled batteries. Our results reveal that, after tens of thousands of high-rate cycles, microcracks emerged on the cathode electrode material (NCM622) particles of the battery, whereas the LTO remained largely unchanged. Additionally, we observed significant electrolyte reduction, characterized the separator surface, and measured its properties. Our findings indicate that the electrolyte reactions are the primary cause of battery failure, leading to capacity fading and impedance increase. This research provides valuable insights into the failure mechanisms of lithium-ion batteries at high rates, thus contributing to the improvement of high-rate lithium-ion batteries.

Chemomechanical Failure of Solid Composite Cathodes Accelerated by High-Strain Anodes in All-Solid-State Batteries

Lithium-ion batteries (LIBs) have played a major role in energy storage, particularly, for portable electronic devices. However, the energy density of the LIB has reached its limit, which is not high enough to fulfill an ever-growing demand for long-lasting batteries. More importantly, safety issues arising from flammable liquid electrolytes are considered critical problems to be addressed for large-scale batteries. All-solid-state batteries (ASSBs) with non-flammable solid electrolytes (SEs) have been emerging as a promising alternative to liquid-electrolyte-based LIBs. Among various types of SEs, sulfide-based materials, e.g., Li6PS5Cl (LPSCl), have gained much attention, owing to their high ionic conductivity at room temperature.To develop ASSBs with high energy density, Li metal/alloys or Li-free Ag-C composites have been widely studied as anode materials; however, they undergo large volume changes during repeated charge-discharge cycling. In addition to the morphological and mechanical degradation of the anode itself, massive volume changes exert additional mechanical stresses on the cell components and interfaces between them, which can cause accelerated performance decay. While a few studies have been reported on the mechanical deformation of the SE layers induced by the volume changes of anodes, possible degradation of the composite cathodes has been largely overlooked.Herein, we present a comparative study of ASSBs assembled with high-strain (Li-In) and zero-strain (Li4Ti5O12 (LTO)) anodes to understand the impact of anode volume changes on chemomechanical degradation behaviors of solid composite cathodes. An ASSB cell was composed of polycrystalline NCA-LPSCl composite cathode, LPSCl separator layer, and either Li-In or LTO anode. The Li-In-based cell suffered from severe capacity loss after 120 cycles, whereas the LTO-based cell showed a stable capacity retention over 200 cycles. Impedance decoupling via three-electrode set-up indicated rapid increases in interfacial and diffusion (Warburg) impedances of the composite cathode in the Li-In-based cell during cycling, as compared with those in the LTO-based cell.In-depth chemical, electrochemical, and microstructural analyses revealed that the high-strain Li-In anode perturbs the structural integrity of the composite cathode and facilitates “dynamic” contacts between the cathode constituents upon repeated cycling. This leads to the enhanced parasitic interfacial reactions, as evidenced by the increased amount of resistive phases (e.g., P2S x , Li2S, and PO4 3-) in the cathode of the Li-In-based cell. The resulting chemically/electrochemically inhomogeneous interfaces between NCA and LPSCl cause localized concentrations of diffusion-induced stress within NCA, leading to the accelerated cracking of NCA aggregates. This study highlights the accelerated degradation phenomena of composite cathodes driven by high-strain anodes and provides insights into the design of ASSBs with long cycle lifetimes.

Fabrication and Characterization of LiNi1/3Mn1/3Co1/3O2/Li0.6La0.4TiO3/Li4Ti5O12 Full Cell All-Solid-State Thin Film Li-Ion Batteries for Energy Applications

Recent days, natural calamities caused by the global warming and climate changes are major concern for the entire globe and there is a pressing need to address such issues to save the mankind from further havoc and devastation. To reduce the carbon emission, countries are shifting dramatically towards renewable sources for their energy needs for their day-to-day life. Li ion batteries are in the forefront of the battle towards the sustainable growth and development due to their high energy density and renewable in nature. In the present case, we report on development of thin film based all-solid-state batteries (ASSB) for energy applications. LiNi1/3Mn1/3Co1/3O2 (NMC), Li0.6La0.4TiO3 (LLTO) and Li4Ti5O12 (LTO) materials are employed as a cathode, solid electrolyte and anode layers for fabricating a full cell all-solid-state thin film batteries. All the layers are fabricated employing RF sputtering technique. Before fabricating the full cell, individual layers are fabricated and their electrochemical and/or ionic conductivity properties are explored. Li0.6La0.4TiO3 solid electrolyte thin films are seen to exhibit room temperature in-plane ionic conductivity in the order of 10-3 S/cm. NMC thin film with the thickness of 100 nm exhibits specific capacity of 91 µAh/cm2 and the redox peaks at 3.8 V and 3.5 V. LTO anode thin films shows the specific capacity close to 100 mAh/cm2and the redox peaks around 1.5 V. XRD pattern of NMC/LLTO/LTO full cell shows the diffraction peaks corresponding to all the three layers. Cross-sectional scanning electron microscope (SEM) image indicates the uniform coating and presence of all the layers. High-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) along with the energy dispersive X-ray is employed to image the cross-sectional details and the elements present in each layer of the full cell all-solid-state thin film battery. Impedance spectroscopy was employed to calculate the total conductivity of the fabricated full cell. Obtained results indicates that the full cell NMC/LLTO/LTO thin film batteries can be fabricated employing a sputtering technique for the energy applications. Figure 1

High-performance graphite||Li4Ti5O12 dual-ion full batteries enabled by in-situ formation of LiF-rich solid electrolyte interphase on Li4Ti5O12 anode

Dual-ion batteries (DIBs), well-known for the high-rate capability of the graphite cathode, urgently need a suitable anode material to realize their high power density in practical applications. In that respect, Li4Ti5O12 (LTO), which can be cycled at high rates for thousands of cycles, can be a good candidate. However, a facile method to stabilize the graphite||LTO full cells is necessary. Herein, we introduce LiDFOB additive into the electrolyte of graphite||LTO cells, which drastically improves the cycling performance and reduces self-discharge of the DIBs. Specifically, by adding 1.0 wt% LiDFOB to 2 M LiPF6 in fluorinated ethyl methyl carbonate, graphite||LTO DIBs can maintain stable charge-discharge for over 8000 cycles at 20 C. Characterizations indicate that LiDFOB forms a robust LiF-rich solid electrolyte interphase (SEI) on the LTO anode to suppress side reactions such as electrolyte decomposition and gas generation.

Scalable Precursor-Assisted Synthesis of a High Voltage LiNiyCo1-yPO4 Cathode for Li-Ion Batteries.

A solid-solution cathode of LiCoPO4-LiNiPO4 was investigated as a potential candidate for use with the Li4Ti5O12 (LTO) anode in Li-ion batteries. A pre-synthesized nickel-cobalt hydroxide precursor is mixed with lithium and phosphate sources by wet ball milling, which results in the final product, LiNiyCo1-yPO4 (LNCP) by subsequent heat treatment. Crystal structure and morphology of the product were analyzed by X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM). Its XRD patterns show that LNCP is primarily a single-phase compound and has olivine-type XRD patterns similar to its parent compounds, LiCoPO4 and LiNiPO4. Synchrotron X-ray absorption spectroscopy (XAS) analysis, however, indicates that Ni doping in LiCoPO4 is unfavorable because Ni2+ is not actively involved in the electrochemical reaction. Consequently, it reduces the charge storage capability of the LNCP cathode. Additionally, ex situ XRD analysis of cycled electrodes confirms the formation of the electrochemically inactive rock salt-type NiO phase. The discharge capacity of the LNCP cathode is entirely associated with the Co3+/Co2+ redox couple. The electrochemical evaluation demonstrated that the LNCP cathode paired with the LTO anode produced a 3.12 V battery with an energy density of 184 Wh kg-1 based on the cathode mass.

Improvement of the rate capability of the Li4Ti5O12 anode material by modification of the surface composition with lithium polysulfide

Partial substitution of oxygen by sulfur was attempted using a Li/Ti rich conditions for the nominal compositions Li4Ti5O12−xSx x = 0.125–0.375. However, a much lower sulfur substitution, i.e. at dopant level, was achieved as deduced from an almost negligible increase in unit cell size observed from X-ray powder diffraction. The sulfur in the samples is mainly deposited on the surface as sulfate and Li2S2 as deduced from XPS. However, most of the nominal sulfur is lost. Interestingly, for nominal x = 0.125 a considerable improvement in performance is achieved compared to undoped LTO. The sample with x = 0.125 not only shows ∼9% higher capacity at slow cycling at C/20, but also has a remarkably better power rate behavior, with a capacity of 125 mAh g−1 at higher 2 C, compared to 79 mAh g−1 for LTO at the same rate. The significant improvement is explained by the formation of lithium polysulfide in the high-temperature reaction and the concomitant Li+ deficiency to form the spinel, causing the reduction of Ti4+ to Ti3+ and the creation of oxygen vacancies with the formation of an oxygen and lithium deficient spinel Li4−y (Ti4+)5−y (Ti3+)y O12−y. Li2S2, detected in the sample with nominal x = 0.125 by XPS and at higher nominal sulfur contents by CV, may prevent carbonation of the spinel surface while providing ionic conductivity upon reduction to Li2S, justifying its better performance. On the other hand, the contribution to capacity from both mass diffusion and the capacitive charge storage mechanism is unaffected, and therefore LTO and surface-modified LTO-S-0.125 are regarded as typical battery materials.

Carbon-coated Li4Ti5O12 particle anchored on reduced graphene oxide for Li-ion batteries

Herein, a disordered carbon and rGO co-modified Li4Ti5O12 (LTO) anode material (LTO/C@rGO) was prepared by a simple hydrothermal reaction. In this anode material, the intermediate carbon layer acts as a bridge to anchor the LTO particles uniformly on the reduced graphene oxide (rGO) sheets to construct a special network structure. The high conductivity of rGO is used to improve the electronic and ionic conductivity of LTO, and the content of rGO is adjusted to achieve the purpose of balancing the electron and ion transport efficiency. When the introduction amount of rGO is 5 wt%, the discharge-specific capacities are 290.0 mAh/g and 249.9 mAh/g of 10 cycles at 200 mA g−1 and 2000 mA g−1, respectively. Therefore, the construction of this special structure plays an ideal role in improving the rate performance and long-cycle stability of LTO anode materials for lithium-ion batteries.

Evaluating the feasibility of the spinel-based Li4Ti5O12 and LiNi0.5Mn1.5O4 materials towards a battery supercapacitor hybrid device

Hybrid devices consisting of energy-dense lithium-ion battery chemistry and power-dense supercapacitors in a single unit cell are vital to improve the energy density of supercapacitors. Herein, we demonstrate a lithium-ion capacitor containing a composite of LiNi0.5Mn1.5O4 and a high surface area carbon composite as the cathode and carbon-coated Li4Ti5O12 as an anode. The composite cathode combines redox and adsorption mechanisms to store ions, producing more capacity. In contrast, the nanostructure anode can store Li-ions through a faster diffusion-type intercalation process. As a result, the lithium-ion capacitor delivers energy densities of 48 and 30 Wh kg−1 at power densities of 250 and 7900 W kg−1, respectively. Furthermore, upon cycling at 1 A g−1, the full cell retains ∼70 % specific capacitance till 4000 cycles. The use of spinel materials in both electrodes boosts the electrochemical performances of this lithium-ion capacitor because of their inherent properties like stable phase and 3D network-type structure for Li-ion diffusion. Additionally, battery-type cathodes like LiNi0.5Mn1.5O4 (4.7 V vs. Li/Li+) with a wider potential window improve the energy density, whereas better safety and cycling stability arise from the zero-strain Li4Ti5O12 anode. The studies on impedance, self-discharge, and leakage current analyses prove the practical feasibility of the lithium-ion capacitor.

Probing Enhanced Electrochemical Performance of Poly (3,4‐ethylenedioxy Thiophene) Encapsulated 5.3 V Spinel LiCoMnO4 Cathode for Li‐ion Batteries

AbstractHerein, the effect of poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT) coating is reported on the electrochemical properties of high voltage, 5.3 V lithium cobalt manganese oxide (LiCoMnO4, LCMO) cathodes. Scalable precipitation followed by a wet coating method is employed for the synthesis of LCMO@PEDOT. Various analytical studies are performed to validate the performance of the cathode. The cycling profile exhibits an enhanced electrochemical performance among the LCMO@PEDOT compared to that of pristine LCMO in a half‐cell configuration. Also, the LCMO@PEDOT: 0.5–3 wt.% is optimized to show better electrochemical performance. The diffusion coefficient calculated from both cyclic voltammetry and electrochemical impedance spectroscopy (EIS) exhibits an increase in the magnitude from PEDOT coating of 0.5 to 3 wt.% in the order of ≈10−12 cm2 s−1. An in‐operando X‐ray diffraction and in‐situ EIS are performed to validate the electrochemical activity. The full‐cell assembly is also fabricated with spinel Li4Ti5O12 (LTO) anode under balanced loading conditions. The LCMO@PEDOT (1–3 wt.%)/LTO exhibits better electrochemical performance compared to pristine LCMO/LTO. In addition, a temperature study of full‐cell is carried out within the range of −10 to 20 °C and compared.
