Abstract: The electrochemical perforrnances of all- solid state lithium battery using polyaniline positive electrode and γ-ray crosslinked PEO electrolyte containing LiClO4/PC solution have been studied.It showed that the ambient temperature conductivity of PEO was over 10-4S/cm as a result of γ-ray irradiation. The capacity of over 60mAh/g and the charge-discharge life of over 68 cycles were achieved for the polyaniline lithium battery. The acimpedance at the Li/PEO interface was much greater than that at PEO/PAn. The result of cyclic voltammetry showed good reversibility of the polyaniline electrode in the lithium battery.
