摘　　要：用化学合成α MnO2做充放电分析,其可充性好于电解二氧化锰(EMD),掺杂Ti后,其充放性能大大提高,X射线衍射证明掺杂后减少了充放电中Mn3O4的生成。The chargedischarge ability of chemically synthesized αMnO2 was proved better than EMD.When it was doped with titanium,its recharge ability was greatly improved.Xray diffraction pattern showed that αMnO2 doped with titanium produced less Mn3O4 during chargedischarge cycles.
