Nickel-zinc batteries offer a reliable energy storage solution for applications that require maintenance-free electrical rechargeability, with good specific energy and cycle life, and low environment impact. The battery design features a nickel oxyhydroxide cathode with an aqueous alkaline electrolyte and a zinc anode.
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. At the positive electrode,
The nickel–cadmium battery system still uses the same positive electrode as the nickel–iron one, while the negative electrode is cadmium. The maximum cell voltage during charge is 1.3 V, and the average cell voltage is 1.2 V. In eqns – , the cell reactions during charging and discharging are presented.
For example, zinc-air batteries are designed to sequester zinc as zinc oxide precipitated in the anode. In this case, the controlled precipitation of ZnO is desirable. On the other hand, zinc-ion batteries are designed to transport zinc ions across the cell to be intercalated into the cathode material.
Primary zinc-air batteries combine an oxygen reduction cathode in an alkaline electrolyte with an anode that is a paste of zinc powder, binder, and electrolyte. The cathode is usually a porous gas diffusion electrode supporting an oxygen reduction catalyst like MnO 2.
Although most zinc-air batteries manufactured today are primary cells, there remain efforts underway to commercialize the technology as a secondary battery. Primary zinc-air batteries combine an oxygen reduction cathode in an alkaline electrolyte with an anode that is a paste of zinc powder, binder, and electrolyte.
