Rechargeable Zn ‐ MnO2 Alkaline Batteries

Recent progress in the development of rechargeable alkaline zinc‐manganese dioxide cells is described. The advantages and limitations of the system are evaluated. Laboratory tests run on commercial primary alkaline cells as well as model simulations of a bipolar electrode show that the rechargeable alkaline battery may be able to compete with lead‐acid, nickel‐cadmium, and secondary lithium cells for low‐ to moderate‐rate applications. However, because of its poor performance at high rates and low temperatures, the alkaline battery is not suitable for present automotive starting applications.
