PURPOSE:To increase the mechanical strength and current collecting ability of electrode by specifying the mixing amount of thermoplastic resin in a secondary battery using a complex comprising a conductive polymer having no conjugated double bond in its principal chain, and thermoplastic resin and conductive material in positive electrode and/or negative electrode. CONSTITUTION:In a secondary battery using a complex comprising conductive polymer having no conjugated double bond in its principal chain, and thermoplastic resin and conductive material in positive electrde and/or negative electrode, the content of the thermoplastic resin is preferably limited to 0.05-0.1 in the weight ratio to the conductive polymer. By specifying the mixing amount of the thermoplastic resin, the mechanical strength of the electrode is increased without sacrifice of conductivity drop before doping. By forming the complex with conductive material, the electrode strength is further increased and current collecting ability is improved. |
