Horizontally Arranged Zn Platelet Deposition Regulated by Bi2O3/Bi toward High‐Rate and Dendrite‐Free 3D Zn Composite Anode

Aqueous Zn-metal battery is considered as a promising energy-storage system. However, uncontrolled zinc dendrite growth is the main cause of short-circuit failure in aqueous Zn-based batteries. One of the most efficient and convenient strategies to alleviate this issue is to introduce appropriate zincophilic nucleation sites to guide zinc metal deposition and regulate crystal growth. Herein, this work proposes Bi
