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: Silicon is a promising active material for lithium-ion batteries with a high theoretical capacity. However, its fabrication requires complicated and high-cost processes to improve cyclic performance. Herein, we report a one-step wet ball-milling process to fabricate submicron silicon particles coated with a polyacrylonitrile (PAN) layer, which enhances electrolyte wettability and increases lithium-ion pathways on the silicon surface. These improvements result in a stable solid electrolyte interphase layer and reduced internal resistance of the electrodes. The silicon anodes with optimal particle size and PAN layer exhibit superior performance even at ultra-fast current density, and when combined with an NCM712 cathode, a full-cell demonstrates excellent performance.

Summary: Transition metals and their oxides are widely studied as anode materials for lithium-ion batteries due to their high theoretical capacities. A porous raspberry-like nickel-enhanced MnO-based carbon-containing composite (Ni/MnO-C) has been successfully synthesized, increasing the specific capacity of LIBs. The porous nanostructure provides buffer space to prevent structural damage and, when broken into smaller nanoparticles, exposes more active sites for additional capacities.

Summary: Coating LiMn2O4 with Al2O3 and PPy using a sol-gel method improves electron conductivity, ion migration rate, and reduces Mn ion dissolution, resulting in enhanced Li ion storage performance of PPy/Al2O3/LMO. This strategy could be applied to synthesize other cathode materials for lithium ion batteries.

Summary: Few-layer phosphorene (FLP) has exceptional physical and chemical properties, and a simple and efficient low melting media-assisted ball milling (LMMBM) approach is developed to prepare FLP in large quantities. The use of liquid medium promotes the slipping/curling of black phosphorus (BP) layers during ball milling. The LMMBM approach also has potential for mass production of other two-dimensional materials.

Summary: In this study, we found that Li1.12Mn0.74O1.60F0.40 positive electrodes with a loose-crystalline rock salt structure show stable and high capacity, with little change in the charge-discharge curve. The introduction of F-Mn bonds in the positive electrode suppresses the local spinel transition in Mn-based positive electrodes.
