Nickel Zinc Battery

Nickel–Zinc Battery. Nickel–zinc has been invented in 1899 and produced commercially from 1920. The positive electrode also uses the same material, and for the anode electrode, a pasting of zinc oxide is used. Due to the high cell voltage, the energy density is about double of the nickel–cadmium and nickel–iron-based batteries.
