摘要
碱锰电池已广泛用于需要大电流放电的电器。为此应对碱锰电池需要进行重新设计。综述了大电流放电碱锰电池研发进展。为了适应大电流放电的要求,对负极锌粉的组成,锌粉粒径的分布,电解液对负极的影响,正极材料EMD的选择条件:包括EMD的功率系数、平均粒径、正极孔隙率以及添加剂的作用;石墨的新近开发,在正极中除了起电子导电功能外,可能有其它作用;EMD与石墨用量比对大电流放电电池性能有较大影响;对隔膜厚度的要求等均作了理论评述。
The application of alkaline Zn/MnO2 cells started to include the electronic devices that required current drains of more than 1 000 mA(for LR6).Fulfilling this demand required a redesign of the cell as a whole.The development of those cells were reviewed:the components of anode active materialzinc powder,its particle size and distribution;the selection conditions for cathode active materialEMD including'power coefficiency',porosity,the role of additives.In addition,the new types of graphite working in positive electrode as a conductive additive might have other function.The effect of the mass ratio of EMD to graphite on the cell performance was discussed.
