In situ formation of solid electrolyte interphase facilitates anode-free aqueous zinc battery

open access: yeseScience
Aqueous Zn batteries (AZBs) suffer from poor Zn anode reversibility. To address this issue, excess Zn foil is often utilized to prolong the cycle life, but it reduces the actual battery energy density. In this work, we use methylurea molecules to in situ

Anode corrosion in aqueous Zn metal batteries

open access: yeseScience, 2023
Given their low cost and intrinsic safety, aqueous Zn metal batteries (AZMBs) are drawing increasing attention in the field of smart grids and large-scale energy storage. However, the Zn metal anode in aqueous electrolyte suffers from a critical issue, corrosion, which must be fully addressed before the practical implementation of AZMBs.
