	Zinc-air batteries are a type of metal-air battery technology that offers the potential for high energy density, inherent safety, and the use of affordable, earth-abundant materials. These characteristics have attracted interest for a wide range of energy storage applications, from hearing aids and sensors to large-scale stationary energy storage. Most zinc-air batteries commercially available today are ''primary cells'' (single-use), but there is growing research and development effort aimed at making zinc-air batteries ''secondary cells'' (rechargeable). This work is driven by the technology's promise to combine high performance with sustainability and low cost.
