无汞二次碱锰电池缓蚀剂的研究

Study on Inhibitors for Mercury-Free Secondary Alkaline Manganese Dioxide Battery

在二次碱锰电池无汞锌负极中加入无机和有机添加剂,通过测定其在未放电及放充循环五次后的析氢量来研究其缓蚀性能。研究表明添加适当量的In_2O_3、PbO、Tl_2O_3及有机物A可在无汞二次碱锰电池中起到很好的缓蚀性能。

Inorganic and organic additives were added into the zinc negative electrode of mercury-free secondary alkaline manganese dioxide battery. The corrosion inhibiting performances of these inhibitors were investigated by determining the hydrogen evolved before discharge and after five cycles. It was indicated that In2O3, PbO , Tl2O3 and the organic compound A had excellent corrosion suppressing function in mercury-free secondary alkaline manganese dioxide battery.
