Triethyl methyl ammonium ionic liquid as an effective electrolyte additive for high-performance zinc–iodine batteries†
Abstract
An ionic liquid (IL)-based electrolyte using a quaternary ammonium IL (triethyl methyl ammonium chloride (N2221Cl)) as an additive is proposed to effectively inhibit the growth of zinc (Zn) dendrites and the shuttling effect of I3− ions, which significantly improves the cycle life of Zn–iodine (I2) batteries (ZIBs).
