Through improving the process technology, primary alkaline battery can be recharged as secondary battery. The charge-discharge reaction mechanism for rechargeable alkaline Zn-MnO2 battery and the effects of over-charge/over-discharge on battery performance were discussed. The electrode design and formula, the process improvement for the rechargeable Zn-MnO2 battery were introduced in this paper. And the charge/discharge performance of rechargeable LR6 battery was compared with that of normal LR6 battery. It was pointed out that, by improvement, the cyclic life of alkaline rechargeable Zn- MnO2 battery could be over 100 times. Finally, the existing problems and resolving methods of reehargeable alkaline Zn-MnO2 battery were analyzed.
