摘要:
The practical implementation of high‐voltage lithium‐rich manganese oxide (LRMO) cathode is limited by the formation of dendrites, unanticipated electrolyte decomposition, and dissolution of transition metal ions. The present study proposes a bi‐affinity electrolyte formulation, wherein the sulfonyl group of ethyl vinyl sulfone (EVS) imparts a highly adsorptive nature to LRMO, while fluoroethylene carbonate (FEC) exhibits a reductive nature towards Li metal. This interface modulation strategy involves the synergistic use of EVS and FEC as ad...
