Summary: This study synthesized a coating layer using lithium bis(oxalato)borate (LiBOB) via low-temperature heat treatment. The LiBOB-coated cathodes heat-treated at 350 degrees Celsius showed improved electrochemical performance and reduced undesired side reactions at the cathode/electrolyte interface compared to the pristine cathode. This LiBOB-based coating is a promising approach to enhance the stability of the cathode/sulfide electrolyte interface.

Summary: This study introduces a gas-solid interface reduction reaction (GSIRR) to improve the interfacial compatibility between cathodes and solid-state electrolytes in all-solid-state lithium-ion batteries (ASSLBs). The application of a surface reconstruction layer (SRL) results in high capacity, remarkable cyclability, outstanding rate capability, and exceptional stability in high-loading cathode. Moreover, the GSIRR mechanism can be applied to various cathode materials and other reducing gases, indicating its practical universality.

Summary: Nickel-rich cathode materials, despite being a promising choice for electric vehicles, face challenges related to long-term cycle life retention and air stability. This study investigates the use of surface treatments, specifically the coating of LiNi0.9Mn0.05Al0.05O2 cathode materials with lithium phosphate, to improve their performance. The results show that low concentration phosphoric acid coating leads to delayed voltage decay and enhanced discharge capacity during high-voltage cycling.
