高性能电解二氧化锰电化性能研究

A Study on A Kind of High Performance Electrolytic Manganese Dioxide

对比测试了研制获得的一种高性能电解二氧化锰和普通商用无汞碱锰电池级电解二氧化锰的理化性能及电性能。用高性能电解二氧化锰制作的LR6无汞碱锰电池，在恒流1000mA，每分钟放电10s，放电截止电压0．9V的放电制度下的放电能力较普通电解二氧化锰提高20％。理化测试结果表明：获得的高性能电解二氧化锰在DTG 150～400℃间重量变化大于4．0％，XRD 2θ67（°）附近衍射峰更明显，峰高更高。

The physical properties, chemical properties and electric properties of a kind of high performance E M D made by ourselves are tested with comparing to normal EMD. The performance of LR6 battery made by the EMD at the discharge style of 1 000 mA,discharge 10 seconds per minute,is promoted 20%. Its lose of weight between temperature 150 - 400° is over 4% and it has special peak on XRD 2θ67（°）.
