Abstract: Because of their low price, excellent safety and energy storage performance, aqueous zinc-ion batteries (ZIBs) have great potential for use in the power grid and in wearable devices. However, the Zn anode of ZIBs is not stable, for example, Zn dendrite can be formed on the Zn anode accompanied by hydrogen evolution and side reactions, leading to its instability, which has been an obstacle to its use. Carbon nanomaterials have recently been used to improve the performance of Zn anodes due to their unique structure, excellent conductivity and good stability. This review summarizes this recent development for stabilizing zinc anodes. The carbon nanomaterials are used are as hosts, protective coating layers, electrolyte additives and modifiers in the separators to stabilize the Zn electrodes. The problems involved in doing this are presented, and some future developments are outlined.
