Abstract

Owing to its high potential, Zn–air battery with a century old technology has been drawing attention recently. However, it is still under research and development stage so that its maximum application has been significantly limited to small portable devices such as just hearing aids. In this article, we briefly introduce possible degradation mechanism of each zinc anode and air cathode and then discuss efforts to address these issues. Furthermore, for making Zn–air battery technology more commercialized, we also discuss the efforts that should be more emphasized and the strategy that can be possible and an alternative for future Zn–air battery technology.
