Abstract

The discharge mechanism of Li/α-Sn(HPO₄)₂ cell has been investigated by means of X-ray diffraction, XPS and cyclic voltammetry methodes. It has been shown that the electrochemical intercalation reation exists in the cathode material. There is a new phase after some degree of intercalation. With potential step and galvanostatic techniques, the chemical diffusion cofficients of Li⁺ in Li_xSn(HPO₄)₂ is estimated to be 10^-12～10^-13 cm²·s^-1.
