Review demonstrates electrodeposited zinc alloy benefits in aqueous metal batteries, highlighting critical design parameters to suppress side reactions and boost reversibility.
The application of aqueous zinc metal batteries (AZMBs) is hindered by uncontrollable plating/stripping and side reactions during the deep cycling of zinc (Zn) foil anodes. Zn alloy anodes overcome the inherent limitations by suppressing parasitic interfacial reactions while guiding controlled plating–stripping, thereby significantly improving reversibility during deep cycling. Electrodeposition allows structural design and functional modulation of alloy anodes, offering solutions to electrode capacity imbalance challenges. Although some reviews have summarized alloy anode strategies in AZMBs, few focus on the theoretical principles and process parameters of electrodeposited Zn alloys, highlighting an urgent need for a systematic understanding in this field. This Review systematically investigates the theoretical mechanisms and process parameters of electrodeposited Zn alloys, establishing an analytical framework. Finally, strategic directions are proposed to advance the understanding and design of electrodeposited Zn alloy systems for AZMBs, providing theoretical frameworks and guidelines.
