The Li/Lil/(CHIy)x battery was fabricated by using fast ionic conductor-LiI as the solid electrolyte has not been reported. The battery exhibited an open circuit voltage of 3.1v and an initial short circuit of 7ma/cm^2. (CHIy)x can be used in the Li/l2 battery as the rote of charge transfer complex. Experimental enerny density of 110Wh/kg was obtained based on the weight of (CH)x film (weight of (CH)x electrode:ca. 4mg, doping level:y=0.11).
