RecommendationsE lectrolyte composition is a major factor that directly dictates the overall behavior of storage batteries.From ionic conductivity to solid electrolyte interphase (SEI) interface, and from the electrochemical window to battery safety, electrolyte design becomes crucial for improving storage batteries' performance and life cycle.In this Spotlight, we highlight two recent advances related to the design of halide electrolytes for all-solid-state batteries and localized saturated electrolytes to tackle the degradation issues of Li//LiNiO 2 storage batteries.
