Aqueous zinc-ion batteries (ZIBs) as a new battery technology have received great attention due to the high energy and power density, low cost, high safety and environmental friendliness. However, their practical deployment has been restricted by some serious issues such as corrosion of zinc metal anode in aqueous electrolyte, undesired growth of zinc dendrites, and hydrogen evolution from the water splitting. Therefore, tremendous efforts have been devoted to mitigate these issues and significant progresses have been achieved. In this paper, we review some key recent progresses of aqueous ZIBs, focusing on materials engineering strategies that are able to address the major challenges. Moreover, we provide rational perspectives on the future development of ZIBs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
