Lithium‐ion batteries with routine carbonate electrolytes cannot exhibit satisfactory fast‐charging performance and lithium plating is widely observed at low temperatures. Herein we demonstrate that a localized high‐concentration electrolyte consisting of 1.5 M lithium bis(fluorosulfonyl)imide in di...
