PURPOSE:To obtain a secondary battery having high power and light weight by forming a positive electrode with electric conductive high polymer and a negative electrode with carbon containing graphite structure. CONSTITUTION:A secondary battery is fabricated by using electric conductive high polymer as a positive electrode, carbon containing graphite structure as a negative electrode, and electrolyte prepared by dissolving a compound capable of electrolytically producing an ion which can be doped into the positive and negative electrodes in a nonaqueous solvent. Performance, espetially energy density, of the secondary battery is substantially increased compared with a secondary battery using conventional electric conductive high polymer. Artificial carbon prepared by carbonizing a substance at a temperature of above 1,000 deg.C and less than 2,500 deg.C, or artificial graphite prepared by graphitizing a substace at 2,500 deg.C or more, or natural graphite is preferable as the carbon containing graphite structure. |
