A rechargeable all‐plastic battery was fabricated using film as the electrode active material and [ in polyvinylidene fluoride (PVDF)] film as the electrolyte. The battery exhibited an open‐circuit voltage of 3.4V, and an initial short‐circuit current of 13 mA (weight of electrode: ca. 4 mg; doping level, ). Experimental energy density of 47 Wh/kg was obtained based on the weight of film (weight of electrode: ca. 4 mg, doping level ). No change in the coulombic and power efficiencies of a battery could be observed even after 300 successive charge‐discharge cycles, although doping level was shallow . The coulombic efficiency was 82%. The ionic conductivity of polymeric solid electrolyte was estimated from a complex impedance analysis.
