Summary: In this study, a suitable surface treatment was designed to optimize the cyclic quality of LiNi0.8Co0.1Mn0.1O2. The results indicate that solvent treatment effectively removes lithium compounds from the material's surface, improving the embedding and release of Li+. The formation of a protective layer and a 3-4 nm thick rock-salt phase NiO on the solvent-treated surface contributes to the stability and enhanced electrochemical performance of the material.

Summary: Thermal runaway, caused by lithium plating in low-temperature cycling LIBs, is a significant hazard that hinders the application of LIBs in electric vehicles and energy storage systems. This study developed a thermal runaway model that includes the exothermic reaction between metal lithium and electrolyte to account for the aging effect. Validation tests confirmed the effectiveness of the model. The results revealed a three-stage process for thermal runaway and demonstrated that the reaction between plated lithium and electrolyte at around 140 degrees C accelerates the onset of thermal runaway.

Summary: This study investigates the effects of charge/discharge cycling on the thermal stability of a high-Ni cathode material, LiNi0.8Co0.1Mn0.1O2. The results show that the bulk structure of the cathode remains unchanged, while a stable rock-salt structure is formed in the surface layer. The formation of the rock-salt layer significantly reduces the heat generation at the lowest temperature, enhancing the thermal stability of the high-Ni cathode.
