无汞可充碱锰电池负极复合添加剂的研究

Composite additives to negative electrodes for mercury-freerechargeable alkaline manganese batteries

通过锌膏集气实验、电池放充电实验及电池内阻测试,对无汞可充碱锰电池负极复合添加剂进行了研究.实验表明,含聚氧乙烯基的非离子表面活性剂和氢氧化铟具有缓蚀协同作用,该复合添加剂能够明显减缓电池的自放电,同时改善可充碱锰电池的电化学性能.

Some composite additives to negative electrodes for mercury-free rechargeable alkaline manganese (RAM) batteries were investigated through gas collection experiments, discharging and charging experiments and internal resistance measurements. These experiments show that some nonionic surfactants containing polyoxyethylene and In(OH)3 have synergistic effect on suppressing corrosion. This kind of composite additives can obviously reduce self-discharge of RAM batteries and improve their electrochemical performance.
