Abstract

Bio-derived quaternary-ammonium-functionalized chitosan (HACC) was investigated as an electrolyte additive for Zn anode stabilization, for the first time to the best of our knowledge. Due to its special structure, including abundant hydrophilic functional groups and positive charge, HACC can inhibit the hydrogen evolution reaction, promote Zn2+ transport, and induce the deposition of Zn(002). Consequently, the electrolyte with HACC exhibits improved electrochemical performance.
