Study on the performances of primary alkaline Zn-NiOOH/MnO_2 battery

A new primary alkaline battery composing of NiOOH / MnO2 cathode and zinc anode was developed. This new type battery improved the performances of conventional primary alkaline Zn-MnO2 battery, which has not good heavy load discharge characteristic. The fresh capacity of primary alkaline Zn-NiOOH / MnO2 battery discharge at constant 1 000 mA to 1.2 V is 3.6 times higher than that of primary alkaline Zn-MnO2 battery. The capacity remain of Zn-NiOOH / MnO2 battery after storage at 71℃ for 7 d is 73.8%, and capacity remain after storage at room for 1 year is 85.6%. Also, the discharge and storage performances of primary Zn-NiOOH / MnO2 battery at different loads were studied.
