通过电子能谱(AES 和ESCA)研究了锂-聚吡咯电池的放电反应,认为该电池的放电是锂在聚吡咯的嵌入过程,嵌入的锂主要是以Li[+]存在,其1s电子的结合能为56.0eV.Li[+]在嵌合物中的扩散系数D为10[-12]一10[-13]cm[2].s[-1]数量级。

A mechanism of electrochem. intercalation is suggested for the discharge of a Li-polypyrrole battery on the basis of experimental data obtained by ESCA and AES. In the intercalation compound Li exists mainly in ionic state with a binding energy of 56.0 eV for Li+ (1s) electron. The diffusion coefficient of Li+ in the intercalation compound is 10-12-10-13 cm2/s.
