Abstract

The effect of electrostatic interaction on regulating an anion-rich solvation in electrolyte is firstly proposed.The moderate electrostatic interaction between anion and solvent promotes anion-rich solvation sheath, inducing a stable electrolyte|electrode interface with fast Li⁺ transport kinetics.The outstanding electrochemical performance of 50 μm-thin Li||high-loading LiCoO₂ batteries is achieved at high voltage of 4.5 V (even up to 4.6 V), lean electrolyte of 15 μL, and wide temperature range of − 20 to 60 °C.
