WebDec 31, 2024 · The chemistry of an alkaline zinc battery is pretty simple on the surface. Zinc metal foil serves as one electrode, with each zinc ion liberating two electrons. WebA commercial zinc–carbon primary battery has a low specific energy of 55–75 Wh kg −1 and an energy density of 120–150 Wh dm −3. The zinc–carbon battery performs better on intermittent discharge than under continuous drains. Rest allows dissipation of the concentration polarization at the zinc anode surface.
