【摘要】 采用正交法变动氯化锌、氯化铵和氯化钙的用量 ,配制电解液 ,加入一种电解液抗冻剂和电池活性剂 ,试制成五号无汞锌锰电池。放电实验表明 :该电池在 - 2 5℃条件下能稳定的释放电能 ,在常温与市售同型号的电池性能相近 ;调整了 p H值 ,增强了电池的耐蚀性 ;采用氯化钙并取消了汞 ,电池成本降低且实现了环保。更多还原

【Abstract】 The electrolyte is prepared with ZnCl 2, NH 4Cl and Ca Cl 2 using orthogonal array ,and added with a kind of antifreezer and cell active agent to make 5# Hg free batteries of Zn MnO 2.The test results show that these batteries could discharge steadily at -25℃,and have similar performance to the same type commercial batteries at the normal temperature.The pH value is re changed to enhance corrosion resistance.The cost of the batteries could be reduced as Hg is replaced of CaCl 2.更多还原
