| 摘 要： | 本文从氧化物半导体观点研究了电池级二氧化锰中氧缺位的扩散和影响扩散常数的因素。使用“恒电位二步极化”法求得与MnO_2中氧缺位扩散性质相关的特征因子“I~o”。并结合样品中MnO_2含量,定量地求得电池级二氧化锰的电化学活性,文中还给出了实验数据和对比电池的实际效分值。二者之间存在着良好的一致性。

| Abstract: | The diffusion of the hole in the battery-active manganese dioxide and factor of the effecting diffusion constant has been studyed from the point of view of oxide semicanductor. A characteristic factor Io with relation to diffusion constant of the vacancy in MnO_2 was obtained. Considering influence of the MnO_2content and using the characteristic factor P. activity of the battery-active mang- ese dioxide could be quantitatively extracted, A better agreement between the exper imental results and discharging times of the practice batteries has been get. |
