Dual-anion chemistry synchronously regulating the solvation structure and electric double layer for durable Zn metal anodes

Abstract

Dual-anion chemistry is engineered by adding strong polarity Ac − into Zn(OTf) 2 electrolyte, which enables synchronous regulation of solvation structure and electric double layer, thereby countering rapid Zn 2+ consumption and prompting favorable interphase formation for durable Zn metal anodes.
