The localized high‐concentration electrolyte (LHCE) propels the advanced high‐voltage battery system. Sulfone‐based LHCE is a transformative direction compatible with high energy density and high safety. In this work, the application of lithium bis(trifluoromethanesulphonyl)imide and lithium bis(flu...
