| 摘 要： | 在一定条件下，用碱金属和碱土金属金属的氯酸盐浆Mn2+氧化制得的化学MnO2，通过对其进行晶型和放电性能的测试，结果表明：所得产品均为γ-MnO2，且γ-MnO2的放电性能与相应的掺杂同族金属阳离子的半径大小变化呈现一定关系。

| Abstract: | Mn 2+ was oxidized to produce Mn O2 samples by metal chlorates (Metal = Li ,Na,K,Mg ,Ca
or Ba) under certain conditions. The resulting MnO2 samples were characterized by infrared spectroscopy,differential thrmal analysis and discharge performance studies. The results showed that all of the poduced samples were γ-MnO2, and the discharge performance of the γ-MnO2 samples was enhanced with ionic sizes of doped metallic cations in the same element group. |
