Summary: By utilizing the flexible porous skeleton of S/N co-doped graphene aerogel (SNGA), NiCoO2 and NiCo2S4 were successfully loaded onto the SNGA surface, leading to improved reversible capacity and rate capability for lithium ion battery anode materials. The high specific surface area carbon source of SNGA contributed to the mitigated particle agglomeration of NiCoO2 and NiCo2S4, while the one-step hydrothermal process of NiCo2S4 resulted in a more compact and coherent porous structure in NiCo2S4/SNGA. These materials exhibit good stability and high rate performance, providing theoretical guidance for the further application of SNGA skeletons in lithium energy storage.

Summary: The current commercial carbonate-based electrolytes cannot meet the increasing voltage requirements of high energy density lithium-ion batteries. It is crucial to construct a robust cathode-electrolyte interphase (CEI) to separate the electrolytes from the cathode materials and suppress side reactions. This review summarizes the historical evolution, characterizations, and modeling of CEI, as well as practical considerations for electrolyte design. The focus is on CEI-forming additives, antioxidation solvents, and lithium salts.
