摘要
分析了球磨处理对电解二氧化锰（EMD）晶体结构、粒径和比表面积的影响，研究了球磨后的EMD对碱性锌锰电池放电性能和过放电防漏性能的影响。球磨处理可使EMD的粒径由40μm降低到15μm，比表面积从25．1m^2／g提高到26．2m^2／g，电池放电性能提高5％～20％，过放电漏液率从50％降低到0％。通过球磨用Ti02、Bi203、BaO和Xb2O3对EMD进行掺杂，可提高电池的电性能。
Effects of ball-milling on crystal structure, particle size and specific surface area of electrolytic manganese dioxide （EMD） were analyzed. The effects on the discharge performance and over-discharge leakage-proof performance of alkaline Zn/ MnO2 battery were studied. By ball-milling, the particle size of EMD was decreased from 40 μm to 15 μm, the specific surface area was increased from 25.1 m^2/g to 26.2 m^2/g, the discharge performance was improved 5 % - 20%, the over-discharge leakage rate was decreased from 50% to 0%. The electric performance of battery with EMD doping with TiO2, Bi203, BaO and Yb2O3 by ball- milling was improved.
