摘要
研制了以NiOOH与MnO2混合作正极活性物质、锌为负极的新一代实用碱性一次电池,弥补了目前广泛使用的碱锰电池大负荷放电性能不佳的缺陷。这种碱性Zn-NiOOH/MnO2电池1000mA大负荷放电至1.2V高压段的容量比碱锰电池提高了3.6倍,71!高温储存7d后,再放电至1.2V时容量保持率可达到73.8%,在室内储存1a后1000mA放电至1.2V的容量保持率还可达到85.6%。对这一新型电池在不同负荷下的放电容量和储存性能也进行了研究。
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.
