A zinc–air battery is a metal–air electrochemical cell powered by the oxidation of zinc with oxygen from the air. During discharge, a mass of zinc particles forms a porous anode, which is saturated with an electrolyte. Oxygen from the air reacts at the cathode and forms hydroxyl ions which migrate into the zinc paste.

This chapter does not have an outline. Zinc-air batteries (ZABs) are a promising non-lithium-containing battery chemistry, which have high theoretical energy densities, abundant constituent materials, low cost, and inherent safety. They are well suited to a range of applications from portable electronics to grid-scale storage.
Zinc-air batteries (ZABs) hold particular promise for applications from portable electronics to grid-scale storage.
Furthermore, zinc–air batteries, both primary and electrically rechargeable, can meet the requirements of the whole range of applications: portable electronics, medium-scale energy production and storage and eventually grid storage.
Rechargeable alkaline zinc–air batteries (ZAB) hold great promise as a viable, sustainable, and safe alternative energy storage system to the lithium-ion battery. However, the practical realization of ZABs is limited by their intrinsically low energy trip efficiency, stemming from a large charge and discharge potential gap.
Zinc–air batteries (ZABs) have been considered as a next-generation battery system with high energy density and abundant resources. However, the sluggish multi-step reaction of the oxygen is the main obstacle for the practical application of ZABs.
