Summary: Laser-induced structures in graphite anodes have been shown to significantly improve the performance characteristics of lithium-ion batteries, including discharge rate capability at different temperatures and discharge/charge rates. The study demonstrated that cells with structured anodes had higher capacity retention after 500 charge and discharge cycles, and post-mortem analyses showed a reduced surface layer formation on the structured anodes compared to their non-structured counterparts.

Summary: Lithium-manganese-oxides have been a promising cathode material with environmental friendliness, resource abundance, and low biotoxicity. However, challenges such as Jahn-Teller distortion, manganese dissolution, and phase transition have hindered the progress of full manganese-based cathode materials (FMCMs). With the increasing demand for vehicle electrification and large-scale energy-storage grids, new research waves focusing on FMCMs are emerging. This review provides a comprehensive examination of the history, structures, advantages, challenges, resolution strategies, and latest developments of FMCMs, as well as discussing controversial topics in Li2MnO3-based cathode materials.

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: The Lithium and Manganese-rich layered oxides with the formula Li1.2Ni0.1Mn0.6Co0.1O2 (LMR-NMC) are considered highly promising cathode materials for next-generation lithium-ion batteries due to their high energy densities, low cost, high thermal stability, and environmental safety. This study synthesized LMR-NMC oxides with different morphologies and analyzed their crystal structures and electrochemical properties. The nanoplatelet-like morphology (LMR-NMC-A) exhibited better performance than the cubic-like morphology (LMR-NMC-B). These findings confirm the suitability of nanoplatelet-like LMR-NMC-A as a cathode material for lithium-ion batteries.

Summary: Despite the advantages of laser electrode structuring, its implementation in industrial battery production is limited due to a lack of knowledge regarding its integration into the manufacturing process chain. This study experimentally evaluated three process integration positions for laser structuring of graphite anodes. The results showed that the material ablation process is influenced by the evaporation of solvent and binder for wet and dry electrodes, respectively. Laser structuring improved the discharge capacity and reduced tortuosity for all structured electrodes, with better performance for dry electrodes.

Summary: Resource constraints have become critical for the Li-ion industry. Spinel LiMn2O4 is proposed as a cheaper and more sustainable alternative to traditional cathodes, but it faces capacity loss due to a two-phase transition. This study demonstrates that introducing disorder can replace the two-phase region with solid-solution behavior, leading to high-capacity cathodes. The results provide guidance on the optimal level of disorder in spinels to achieve solid-solution behavior and good Li mobility, and suggest the potential of utilizing disorder to mitigate problematic phase transformations.

Summary: Li-x(Ni0.4Mn0.4Co0.2)O-2 powders were obtained by chemically delithiating Li-1.11(Ni0.4Mn0.4Co0.2)O-2 powders using (NH4)(2)S2O8 oxidizer. The thermal behavior of two delithiated specimens, Li0.76Ni0.41Mn0.42Co0.17O2.10 and Li0.48Ni0.38Mn0.46Co0.16O2.07, was studied and compared to the pristine specimen. Phase transitions at elevated temperatures were investigated using simultaneous thermal analysis (STA) and the gas evolution during the phase transitions was analyzed. The enthalpies of formation were calculated based on the measured enthalpies of two delithiated samples and a pristine specimen.
