In this work, graphite-based negative electrode for lithium-ion battery consisting a novel and biodegradable binder poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) is compared with standard graphite electrode with polyvinylidene fluoride (PVDF) as a binder. The rate and cycling performance of lithium ion insertion/extraction of electrodes with PHBV in a half-cell configuration are evaluated. Moreover, on the basis of the electrochemical tests it is concluded that the electrode with PHBV binder is characterized by similar specific capacity and diffusion coefficient of lithium ions as conventional graphite electrode with PVDF binder.

Insight into the Origin of the Rapid Charging Ability of Graphene-Like Graphite as a Lithium-Ion Battery Anode Material Using Electrochemical Impedance Spectroscopy

Graphene-like graphite (GLG), a carbon material synthesized by heat treatment of graphite oxide, can be charged at a high rate without deposition of lithium metal even when the potential of the GLG anode is stepped below the Li deposition potential. However, the factors contributing to this outstanding rapid chargeability of GLG have been unclear until now. In this study, to clarify the factors, the charge-transfer resistance and diffusion resistance of GLG were quantitatively evaluated by the electrochemical impedance method using GLG thin films as model electrodes. The activation energy of lithium-ion transfer at the GLG/electrolyte interface was found to be almost the same as that reported for graphite, and it was clear that this process was as slow as that in graphite. On the other hand, the lithium-ion diffusion coefficient in GLG calculated from the Warburg impedance was several orders higher than that of graphite, which clearly shows that this contributed greatly to the fast-charging characteristics of GLG. In addition, in the comparison among GLGs with different structural parameters, the lithium-ion diffusion coefficient was higher for those with less oxygen content and more pores formed in the graphene layer inside the GLG. Therefore, it was concluded that a high diffusion coefficient was ascribed to the pores in the GLG, which enabled lithium-ion diffusion in the c-axis direction.

Electrochemical behavior of Sn-doped Li1.2V3O8 cathode materials for Lithium-ion batteries

The discharge capacity of Li1.2V3O8 is obviously decreased, and the diffusion coefficient of lithium ion is relatively low. In order to improve the electrochemical performances of Li1.2V3O8, the study of Sn4+ doped Li1.2V3O8 is performed. The initial discharge capacity of Li1.2V2.97Sn0.03O8 is lower than that of Li1.2V3O8. However, the discharge capacity of Li1.2V2.97Sn0.03O8 is higher than that of Li1.2V3O8 from the second cycle, and the discharge capacity of Li1.2V2.97Sn0.03O8 are significantly improved at high current density. At 50, 100 and 200 mA g−1, the discharge capacities of Li1.2V2.97Sn0.03O8 are 271.8, 268 and 257.2 mAh g−1, respectively. The discharge capacity is maintained at 264.7, 259.6 and 238.3 mAh g−1, after 50 cycles at room temperature. Furthermore, the electrochemical reactivity of vanadium in Li1.2V3O8 electrodes could be improved by Sn4+ doping. Thus, the electrochemical reaction kinetics and the electrochemical properties of Li1.2V2.97Sn0.03O8 are improved.

A facile and energy-saving preparation of α-ZnMoO4 nanorods for enhanced Li-ion intercalation application

In this paper, one-dimensional α-ZnMoO4 nanorods with diameter of 30–50 nm have been prepared by a facile chemical precipitate reaction. This route is facile, energy-saving, no required special equipment and suitable for scalable synthesis. Transmission electron microscopy and fast Fourier transform pattern illustrate that the nanorods grow along the [011] crystal plane. When used as anode of lithium-half cell, the as-synthesized α-ZnMoO4 nanorods deliver a high capacity of about 417.6 mAh g−1 after 800 cycles at the current density of 0.2 A g−1, an excellent rate (140 mAh g−1 even at 2.0 A g−1) and fast lithium-ion diffusion coefficient (2.29 × 10−17 cm2 s−1), which is superior to that of the bulk counter and the previously reported. Such remarkable electrochemical performance is probably attributed to the favorable nanorods characteristic.

Electrochemical Properties of LiFePO4 Cathodes: The Effect of Carbon Additives

The influence of different conductive additives (carbon nanofibers (CNFs), carbon nanoplatelets, and pyrolytic carbon from sucrose (Sucr) or polyvinylidene fluoride) on the morphology, electron conductivity, and electrochemical performance of LiFePO4-based cathodes was investigated to develop the most efficient strategy for the fabrication of high-rate cathodes. Pyrolytic carbon effectively prevents the growth of LiFePO4 grains and provides contact between them, CNFs provide fast long-range conductive pathways, while carbon nanoplatelets can be embedded in carbon coatings as high-conductive “points” which enhance the rate capability and decrease the capacity fading of LFP. The LiFePO4/CSucr/CNF showed better performance than the other cathodes due to the synergy of the high-conductive CNF network (the electronic conductivity was 1.3 × 10−2 S/cm) and the shorter Li+ ion path (the lithium-ion diffusion coefficient was 2.1 × 10−11 cm2/s). It is shown that the formation of composites based on LFP and carbon nanomaterials via mortar grinding is a more promising strategy for electrode material manufacturing than ball milling.

Correlating Morphological and Structural Evolution with the Electrochemical Performance of Nickel-Rich Cathode Materials: From Polycrystal to Single Crystal

Nickel-rich layered oxides (Ni ≥ 90%) have been recognized as a promising cathode material for Lithium-ion batteries (LIBs) owing to their high energy density and low cost. Herein, we prepared 20 LiNi0.90Co0.06Mn0.04O2 (Ni90) samples with various morphologies by regulating sintering temperature and the lithium to transition metal ratio. The correlation between the synthesis conditions, structural properties, and electrochemical performance of Ni90 materials was thoroughly investigated during the evolution from polycrystal to single crystal. A positive and linear relationship was found between sintering temperature and primary particle size (PPS), which affect the electrochemical performance profoundly. Polycrystals with small PPS show a high discharge capacity and low polarization, while single crystals with large PPS have low discharge capacity but excellent cycling stability. Moreover, the sluggish kinetic properties of Ni90 materials at the end of discharge (a sharp drop in lithium-ion diffusion coefficient at the end of discharge) lead the morphology factors to a critical feature that dominates the total discharge capacity. Taking discharge capacity and cycling stability into integrated consideration, the quasi-single crystal Ni90 materials with moderate PPS and the lowest cation disordering is the first choice. These findings contribute to a better understanding of polycrystalline and single-crystal Nickel-rich cathode materials for LIBs.

Liquid Processing of Interfacially Grown Iron-Oxide Flowers into 2D-Platelets Yields Lithium-Ion Battery Anodes with Capacities of Twice the Theoretical Value.

Iron oxide (Fe2 O3 )is an abundant and potentially low-cost material for fabricating lithium-ion battery anodes. Here, the growth of α-Fe2 O3 nano-flowers at an electrified liquid-liquid interface is demonstrated. Sonication is used to convert these flowers into quasi-2D platelets with lateral sizes in the range of hundreds of nanometers and thicknesses in the range of tens of nanometers. These nanoplatelets can be combined with carbon nanotubes to form porous, conductive composites which can be used as electrodes in lithium-ion batteries. Using a standard activation process, these anodes display good cycling stability, reasonable rate performance and low-rate capacities approaching 1500 mAh g-1 , consistent with the current state-of-the-art for Fe2 O3 . However, by using an extended activation process, it is found that the morphology of these composites can be significantly changed, rendering the iron oxide amorphous and significantly increasing the porosity and internal surface area. These morphological changes yield anodes with very good cycling stability and low-rate capacity exceeding 2000 mAh g-1 , which is competitive with the best anode materials in the literature. However, the data implies that, after activation, the iron oxide displays a reduced solid-state lithium-ion diffusion coefficient resulting in somewhat degraded rate performance.

Construction of high sulfur loading electrode with functional binder of polyacrylic acid polymer grafted with polyethylene glycol for lithium/sulfur batteries

Construction of high sulfur loading is crucial for the development of high energy density lithium/sulfur batteries. The binder is indispensable for constructing high active material loading electrode. Here, cross-linked polymeric network of polyacrylic acid polymer grafted polyethylene glycol (PAA-g-PEG) as functional binder has been developed for constructing high sulfur loading electrode in lithium/sulfur batteries. The cross-linked structure of PAA-g-PEG polymer binder has enhanced the active material adhesion, mechanical properties, which decreased overpotential polarization, improved the lithium ions diffusion coefficient, and reduced the self-discharge. More importantly, the PAA-g-PEG functional binder could alleviate the expansion of high sulfur loading electrode. Due to the above advantages, the carbon nanotubes modified sulfur electrode (CNTs@S; sulfur content: 84.3%) with PAA-g-PEG binder obtains the first discharge specific capacity of 795 mAh g−1 at 2.56 mA cm−2 (0.3 C) under a sulfur loading of 5.1 mg cm−2, with a decay rate of 0.07% per cycle over 200 cycles. Even with the high sulfur loading of 9.6 mg cm−2, the CNTs@S electrode exhibits an initial area capacity of 9.5 mAh cm−2 at a current density of 1.61 mA cm−2, and the capacity retention of 97.5% over 50 cycles.

Morphology and Particle Size of a Synthesized NMC 811 Cathode Precursor with Mixed Hydroxide Precipitate and Nickel Sulfate as Nickel Sources and Comparison of Their Electrochemical Performances in an NMC 811 Lithium-Ion Battery

Cathode precursors of lithium-NMC 811 were synthesized by the coprecipitation method using two different nickel sources, namely mixed nickel–cobalt hydroxide precipitate (MHP) and nickel sulfate. The characteristics of the synthesized precursors were compared with the characteristics of the commercial NMC 811 cathode precursor obtained from the international market. The XRD analyses identified that the diffraction peaks of the three precursor materials were in close agreement to that of Li0.05Ni0.75Co0.1Mn0.1O2, with the figure(s) of merit (FoM) of 0.81, 0.88, and 0.9, respectively, for the synthesized precursor that used MHP as the source of nickel (SM-LNMCO-811), nickel sulfate as the source of nickel (SX-LNMCO-811), and the commercial precursor (K-NMC-811). The elemental analysis of the synthesized precursors revealed the Ni:Mn:Co mol ratios of 0.8:0.08:0.12 and 0.76:0.11:0.13 for SM-LNMCO-811 and SX-LNMCO-811, respectively. The SEM analysis revealed that SX-LNMCO-811 and K-NMC-811 showed a similar particle morphology with a spherical shape; the SM-LNMCO-811 exhibited an irregular particle morphology. The particle size analysis showed that SM-LNMCO-811 had the largest average particle size (285.2 μm) while K-NMC-811 and SX-LNMCO-811 samples had almost the same average values (i.e., 18.28 and 17.16 µm, respectively). The results of the charge–discharge measurement of the fabricated battery cylindrical cells with SM-LNMCO-811, SX-LNMCO-811, and K-NMC-811 as cathode materials showed the best discharge value of the SX-LNMCO-811 sample at 178.93 mAh/g with an initial efficiency of 94.32%, which is in line with the electrochemical impedance measurement results that showed the largest ion conductivity and lithium ion diffusion coefficient value of the SX-LNMCO-811 sample that utilized the synthesized nickel sulfate as the source of the nickel.

Bifunctional hydrogen-bonding cross-linked polymeric binder for high sulfur loading cathodes in lithium/sulfur batteries

Construction of high sulfur loading electrode is one of the effective ways to achieve high specific energy density lithium/sulfur batteries. Therefore, the optimization of polymeric binders has been considered as effective strategy to improve the volume changes of sulfur electrodes during charge/discharge processes. In this work, an effective route for the preparation of three dimensional polymeric binder (PAA-PANI) via multiple hydrogen bonds was developed and fabricated through in situ polymerization between polyacrylic acid (PAA) and polyaniline (PANI), which possess bifunctional effects on high sulfur loading cathodes in lithium/sulfur batteries. The carboxyl polar groups of PAA could effectively adsorb polysulfides and the conductive PANI enhance the electronic conductivity of the sulfur electrode. The three dimensional polymeric binder of PAA-PANI has enhanced the active material adhesion, mechanical properties and electronic conductivity, which decreased overpotential polarization, improved the lithium ions diffusion coefficient, and reduced the self-discharge. More importantly, the PAA-PANI functional binder could alleviate the expansion of high sulfur loading electrode. Taking advantages of PAA-PANI binder, the carbon nanotubes modified sulfur electrode (CNTs@S; sulfur content: 84.3 wt%) with PAA-PANI binder exhibits an initial discharge capacity of 906 mAh g–1 at 2.56 mA cm–2 (0.3 C) under a sulfur loading of 5.1 mg cm–2. Even at higher current density of 8.54 mA cm–2 (1 C), the PAA-PANI binder electrode delivers a high capacity of 846 mAh g–1. Moreover, with an extremely high areal sulfur loading of 17 mg cm–2, the cathode shows an areal specific capacity of 16.7 mAh cm–2.

Decreased Deformation and Heat as well as Improved Interface and Diffusion of Silicon To Enhance Electrochemical Performance and Safety by a Negative Thermal Expansion Material

Severe deformation, thermal runaway, and low ionic migration do harm to the applications of silicon. Herein, a negative thermal expansion material of LiTi2(PO4)3 (LTP) with high ionic conductivity was synthesized and utilized to modify nanoscaled Si, and its effects were investigated. Si modified with 3 wt % LTP (SL3) shows the best performance, and its discharge capacities retain 849.4 and 410.9 mAh/g after 100 cycles at 2 A/g as temperatures are 25 and 60 °C, respectively, about 245.4 and 399.9% higher than those of Si. At 60 °C, the diffusion coefficient of lithium ions in Si is increased by 26 times, while the voltage difference between the main redox peaks, charge transfer resistance, and strain of the SL3 are 0.43 V, 171.4 Ω/cm2, and 211 με, respectively, around 15.7, 94.8, and 45.3 lower than those of the Si. The released heat of SL3 is declined to 175.4 J/g, about 85.9% that of the Si. The improvement mechanism of Si by LTP is discussed. It provides a path for enhancing the performance and safety of materials by decreasing heat and deformation hazards, improving the interface, and intensifying transfer.

Camphene-derived hollow and porous nanofibers decorated with hollow NiO nanospheres and graphitic carbon as anodes for efficient lithium-ion storage

A synthesis strategy for hollow and porous nanofibers comprising hollow NiO (H-NiO) nanospheres formed via nanoscale Kirkendall diffusion and supported over a porous graphitic carbon matrix (H-NiO@HNFs) is reported herein to enable the fabrication of advanced anodes for stable lithium-ion batteries (LIBs). The H-NiO@HNFs comprising 1D longitudinal hollow channels ensured efficient diffusion of charged species via effective electrolyte percolation besides providing sufficient space to accommodate the large volume variations during repeated cycling. The hollow NiO nanospheres acted as chemical sites for lithiation and delithiation. Additionally, the H-NiO@HNFs exhibited improved lithium-ion storage properties, such as reasonable rate capability, stable prolonged cyclability at a high current density (1.0 A g-1), and a high lithium-ion diffusion coefficient, primarily owing to their enhanced structural integrity compared to that of filled NiO nanofibers (F-NiO NFs). This facile synthesis approach could broaden the current understanding of 1D hollow nanostructures decorated with conventional hollow metal-oxide nanoparticles for various applications.

Preparation of D-A-D conjugated polymers based on [1,2,5]thiadiazolo[3,4-c]pyridine and thiophene derivatives and their electrochemical properties as anode materials for lithium-ion batteries

Based on the fact that D-A-D CPs (donor-acceptor-donor conjugated polymers) can significantly improve the lithium-ion storage performance of anode materials, three D-A-D CPs (PMTP, PMOTP, and PDOTP) were prepared by simple chemical polymerization reactions with [1,2,5] thiadiazole [3,4-c] pyridine as the acceptor unit and methylthiophene (MTh), methoxythiophene (MOTh), and 3,4-ethylenedioxythiophene (EDOT) as the donor unit, respectively. Each polymer was compounded in situ with the carbon nanotubes (CNTs) to prepare the PMTP@CNT, PMOTP@CNT, and PDOTP@CNT, respectively, all of which were used as the anode materials for the lithium-ion batteries. The capacities of PMTP, PMOTP, and PDOTP were 762.6, 933.4, and 1351.4 mAh g−1 after 160 cycles at 0.1 A g−1, respectively. The order of magnitude of the specific capacity of the three polymers was PDOTP > PMOTP > PMTP, which was due to the fact that with the increasing electron-donating ability of the donor unit of the polymer, the LUMO energy level gradually decreased, the HOMO energy level gradually increased, and the Eg gradually decreased, resulting in an increase in its redox ability and conductivity. The Galvanostatic intermittent titration technique (GITT) showed that the lithium-ion diffusion coefficients of the three electrodes were comparable. XPS demonstrated that lithium ions were mainly stored on the CC and CN of the three polymers (PMTP, PMOTP, and PDOTP). The b-values showed that their electrochemical reactions were controlled by both the internal solid-phase diffusion process and capacitive process. The CV, GCD, cycling stability performance, and rate capability tests showed that all the three electrodes had good electrochemical performance, among which PDOTP@CNT had the best performance and was well suited as the anode material for the Li-ion battery. D-A-D CP provides a new pathway for the development of electrode materials for high-capacity lithium-ion batteries.

Prolate carbon architecture as a novel Li-ion battery anode with kinetic study

Lithium-ion battery (LIB) performance can be tailored by controlling the structure, texture, defects, dopants, and architecture of carbon-based anodes. In this publication, a novel prolate carbon-shape with dual short-ordered graphite-like and turbostratic arrangements was studied for the first time in LIB anodes which delivered a promising reversible capacity of 271 mAh g−1 at 100 mA g−1 after 100 cycles. The novel prolate carbon was synthesized by dry autoclaving avocado oil, utilizing autogenic pressure to ensure a homogeneous sample. The novel prolate carbon demonstrated stable, promising performance by leveraging graphite-like layers towards the surface and a highly amorphous bulk. Physico-chemical and extensive electrochemical studies were conducted to elucidate the Li-ion storage mechanism of the novel architecture: the anode was found to rely on 70% of its lithium to be stored via capacitance, and its apparent lithium-ion diffusion coefficients were estimated in the range between 10−9 and 10−12 cm2 s−1.

Cationic Covalent Organic Framework as Separator Coating for High-Performance Lithium Selenium Disulfide Batteries

Selenium disulfide that combines the advantages of S and Se elements is a new material for Li-chalcogen battery cathodes. However, like Li-S batteries, the shuttle effect seriously restricts the performance of Li-SeS2 batteries. In this work, we have synthesized a kind of nitrogen-rich lithophilic covalent organic framework (ATG-DMTZ-COF) as a separator coating material for Li-SeS2 batteries. Here, the N atom in the ATG-DMTZ-COF channel preferentially interacts with the lithium ion in the electrolyte to form N…Li bond, which significantly improves the diffusion coefficient of lithium ions during the charge and discharge. More importantly, we prove that the pore size of ATG-DMTZ-COF will decrease sharply because there is a large amount of TFSI- in the channel, and finally the shuttling of polysulfide and polyselenide is suppressed by the sieving effect. As a consequence, Li-SeS2 batteries using the ATG-DMTZ-COF separator coating show excellent performances with an initial discharge capacity of 1028.7 mAh g−1 at 0.5 C under a SeS2 loading of 2.38 mg cm−2. Furthermore, when the current density is 1C, the specific capacity of 404.7 mAh g−1 can be maintained after 700 cycles.

Electrochemical characterization of CuF2/CNTs cathode materials prepared by a coprecipitation method

Carbon nanotubes (CNTs) were proposed to improve the electrochemical performances of copper fluoride (CuF[Formula: see text] via a coprecipitation method. FE-SEM and TEM results proved that the three-dimensional conductive network was constructed by the addition of CNTs in the composites, in which some CuF2 particles attached to the outside of CNTs, and some of them grew inside the tube. According to the charge–discharge tests, with CNTs content increasing from 0 wt.% to 30 wt.%, the initial discharge capacities of CuF2 increased from 461 to 571 mAh/g, which exceeded the theoretical specific capacity of the CuF2. Moreover, the electrodes with CNTs exhibited better reversibility and rate performance than the bare electrode. CV and EIS results confirmed that the enhancements could be attributed to the inhibition of the electrochemical polarization of the electrode and the improvement on the diffusion coefficient of lithium ion in the electrode by the addition of CNTs.

Cobalt-free nickel-rich layered LiNi0.9Al0.1-xZrxO2 cathode for high energy density and stable lithium-ion batteries

BackgroundTo meet the challenges of limited resources and the toxicity of cobalt, cobalt freed Ni-rich layered cathode materials for high energy density power batteries have become a hot spot. However, the poor stability upon cycling hindered their applications. MethodsA layered Zr-introduced Ni-Al based Co-free cathode material LiNi0.9Al0.1-xZrxO2 (NAZ) is designed and synthesized with a sol-gel method. Significant findingsThe prepared Co-free cathode material exhibits perfect crystal structure stability and electrochemical performance, which are attributed to the incorporation of Zr4+ with high-valence and strong Zr-O bond energy. The obtained LiNi0.9Al0.08Zr0.02O2 (NAZ-2) shows a first discharge capacity of 177.5 mAh g−1 at 1 C, and maintains about 92.45 % after 100 charge / discharge cycles. It also displays a high specific capacity of 160 mAh g−1 at 5 C. Furthermore, compared to the pure sample, LiNi0.9Al0.08Zr0.02O2 (NAZ-2) shows a lower charge transfer impedance of 57.90 Ω and larger diffusion coefficient of lithium ions of 5.70217 × 10−9 cm2 S−1, which is conducive to the migration of Li+ and the inhibiting of the polarization.

Defect-engineered TiO2 nanocrystals for enhanced lithium-ion battery storage performance

TiO2 nanocrystals containing oxygen defects were successfully prepared by a hydrothermal method with reductive sintering in a 5% H2 + 95% Ar mixed atmosphere. The high-resolution transmission electron microscopy and X-ray diffraction results showed that the prepared samples were all anatase TiO2. X-ray photoelectron spectroscopy analysis showed that the reductive sintering converted Ti4+ to Ti3+. The Ti3+/Ti4+ molar ratio of the TiO2 nanocrystals increased with increasing sintering time. The results of the electron paramagnetic resonance spectroscopy analysis showed that the reduced and sintered TiO2 nanocrystals produced strong signals at g = 2.0010 and 1.9478, corresponding to the presence of oxygen defects and Ti3+, respectively. Furthermore, stronger signals were generated with increasing sintering time, indicating a progressively higher concentration of oxygen defects. The TiO2 nanocrystalswere used as anode materials for lithium-ion batteries. One sample, H-TiO2-5, containing a moderate concentration of oxygen defects, presented a higher lithium ion diffusion coefficient (D = 5.1 × 10-13 cm2s−1) compared to the other TiO2 samples. This sample had a Ti3+/Ti4+ molar ratio of 0.179 and excellent cycling stability after 100 cycles. The discharge capacity was 124 mAh.g−1 after 500 cycles at a current density of 1C, which means that it has good cyclic stability.

Effect of succinonitrile on ion transport in PEO-based lithium-ion battery electrolytes

We report the ion transport mechanisms in succinonitrile (SN) loaded solid polymer electrolytes containing polyethylene oxide (PEO) and dissolved lithium bis(trifluoromethane)sulphonamide (LiTFSI) salt using molecular dynamics simulations. We investigated the effect of temperature and loading of SN on ion transport and relaxation phenomenon in PEO-LiTFSI electrolytes. It is observed that SN increases the ionic diffusivities in PEO-based solid polymer electrolytes and makes them suitable for battery applications. Interestingly, the diffusion coefficient of TFSI ions is an order of magnitude higher than the diffusion coefficient of lithium ions across the range of temperatures and loadings investigated. By analyzing different relaxation timescales and examining the underlying transport mechanisms in SN-loaded systems, we find that the diffusivity of TFSI ions correlates excellently with the Li-TFSI ion-pair relaxation timescales. In contrast, our simulations predict distinct transport mechanisms for Li-ions in SN-loaded PEO-LiTFSI electrolytes. Explicitly, the diffusivity of lithium ions cannot be uniquely determined by the ion-pair relaxation timescales but additionally depends on the polymer segmental dynamics. On the other hand, the SN loading induced diffusion coefficient at a given temperature does not correlate with either the ion-pair relaxation timescales or the polymer segmental relaxation timescales.

Enhance performance of Li1.2Mn0.54Ni0.13Co0.13O2 cathodes via B3+ doping owe to the suppression of spinel phase generates

Boron element was doped into the lithium rich layered oxide Li1.2Mn0.54Ni0.13Co0.13O2 (0%-BLMNC) by ball mill spray drying. B3+ was successfully doped to LMNC particles inside the stability of the crystal structure, reduced the voltage capacity attenuation. TEM measurements showed that the (003) crystal plane spacing of Li[Li0.19Mn0.53Ni0.12Co0.12]B0.01O2 (1%-BLMNC) samples increased from 0.47 to 0.476 nm compared with 0%-BLMNC samples, thus increased the lithium layer spacing from 2.691 Å to 2.952 Å. EIS results also indicated that the lithium ion diffusion coefficient raised from 8.62 × 10−18 cm2s−1 to 1.66 × 10−17 cm2s−1. For half-battery, initial discharge specific capacities of 0%-BLMNC and 1%-BLMNC samples were 193.8 mAh g−1 and 176.6 mAh g−1, respectively. Moreover, after 100 cycles, the volume retention rate of 1%-BLMNC samples was 87.1%, while that of unmodified samples was only 62.5%. For full batteries, the capacity retention of 1%-BLMNC samples after 100 cycles was increased by nearly 15% compared with the matrix. Through material failure analysis, it was further verified that boron doped prevented the transfer of transition metal to lithium layer, stabilized the layered structure and inhibited its phase transition to spinel phase.
