Lithium metal is an ideal anode material for rechargeable batteries, but lithium dendritic growth and limited Columbic efficiency prevent its applications. Here, the authors report the use of highly concentrated electrolytes composed of ether solvents and the salt lithium bis(fluorosulfonyl)imide to enable high-rate cycling of lithium anode.
