Summary: In this study, a new method of sodium tungstate-assisted sintering was proposed to fabricate high-performance single-crystal lithium-rich layered oxides (LLOs) cathode materials. The sodium tungstate promotes particle growth and forms a protective coating on the surface of LLOs particles, suppressing side reactions at the cathode/electrolyte interface. Additionally, trace amounts of sodium and tungsten doping stabilize the crystal structure and enhance the diffusion rate of Li+ ions.

Summary: Lithium-ion batteries (LIBs) are crucial for the electric vehicle (EV) industry, and LiNi1-x-yCoxMnyO2 (NCM) is the dominant cathode material used in EV LIBs. Due to the need for increased driving range, Ni content in NCM is maximized, but the resulting Ni-rich NCM is unstable. Doping with foreign elements has been explored as a strategy to overcome this instability, with over 46 elements considered and their effects on LIB performance investigated in numerous research articles. This comprehensive analysis of various doping elements and their impact on LIB performance provides valuable insights for the LIB industry and academia.

Summary: Research revealed a two-phase reaction scheme in lithium titanium oxide during lithium-ion battery operation, with distinct structural transformations observed at different scales. Linear, reversible changes in bond distance between titanium and oxygen atoms were observed at the atomic scale, while hysteresis in lattice parameter between discharge and charge reactions was noted at the microscale. These differences in structural changes were attributed to variances in spatial resolutions between XAS and XRD techniques.

Summary: Through doping B3+ using a high-temperature solid-phase method, the electrochemical properties of the LiNi0.815Co0.15Al0.035O2 cathode (NCA) were significantly improved. X-ray diffraction analysis and Rietveld refinement showed that B3+ enhanced lattice ordering by minimizing Li+/Ni2+ mixing. Scanning electron microscopy observations indicated that B3+ doping changed the particle morphology. The specific discharge capacities of 1.5% B-NCA were 178.31 and 123.74 mAhg 1 at 0.2 and 5C, respectively. After 100 cycles, the specific discharge capacity was 176.29 mAhg 1 at 0.2C with a capacity retention of 98.87%. Boron doping significantly improves the structural stability of nickel-rich cathode materials by suppressing the detrimental H2 & RARR;H3 phase transition, thus improving the electrochemical performance of nickel-rich ternary lithium-ion batteries.

Summary: CAMs offer higher specific capacities than graphite, but face challenges in maintaining a stable SEI due to significant volume changes. This study focuses on the SEI composition and evolution on transition metal doped zinc oxide as a CAM model compound, revealing that the presence of iron triggers electrolyte decomposition, which can be mitigated by stabilizing the interface with a carbonaceous coating. These findings advance the understanding of doped materials and metal oxide active materials.
