Abstract

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.
