A dendrite-free and anticaustic Zn anode enabled by high current-induced reconstruction of the electrical double layer

Aqueous Zn-based batteries deliver thousands of cycles at high rates but poor recyclability at low rates. Herein, we reveal that this illogical phenomenon is attributed to the reconstructed electrode/electrolyte interface at high rates, wherein the condensed electrical double layer (EDL) and the tig...

Description
Summary:Aqueous Zn-based batteries deliver thousands of cycles at high rates but poor recyclability at low rates. Herein, we reveal that this illogical phenomenon is attributed to the reconstructed electrode/electrolyte interface at high rates, wherein the condensed electrical double layer (EDL) and the tightly absorbed Zn 2+ ions on the Zn electrode surface afford compact and corrosion-resistant Zn deposits. The densely textured and corrosion-resistant Zn anode was achieved by reconstructing the EDL structure via high current density, enabling durable battery performance.
