QWQiying WangSun Yat-sen University RCR. CaoSun Yat-sen University BWBin WangShenyang Institute of Engineering

Key Points

The research aims to address interfacial instability of zinc metal anodes in aqueous zinc-ion batteries.
Investigated the effects of polyvinyl alcohol on zinc metal anodes
Analyzed dendritic growth and corrosion rates
Conducted stability tests in simulated AZIB conditions.
Polyvinyl alcohol significantly reduces dendritic growth rates
Corrosion of zinc anodes is minimized with solvation regulation
Stable zinc metal anodes exhibit improved performance in energy storage.

Abstract

Aqueous zinc-ion batteries (AZIBs) are attractive for large-scale energy storage but remain limited by interfacial instability of zinc metal anodes (ZMAs), including dendritic growth, corrosion, and parasitic hydrogen evolution. Herein,...
