Zinc–air batteries have attractive theoretical energy density of 1086 Wh/kg including oxygen but it is quite lesser than Li–air batteries, which is 1910 Wh/kg (Imanishi & Yamamoto, 2014). These batteries can be manufactured at low costs due to zinc compatibility with an aqueous alkaline as compared nonaqueous-based cells.

... The power densities of batteries with zinc foil and zinc gel electrodes range from 10 to 180 mW cm −2 and 10 to 100 mW cm −2 , respectively. The power densities of batteries using different types of zinc pellets differ considerably from each other resulting largely from differences in collector design .
Zinc–air batteries provide a great potential for future large-scale energy storage. We assess the test factors that mainly affect the measured power density of the zinc–air battery.
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 and form zincate (Zn (OH)2−
