PURPOSE:To improve the cell performance by composing a positive electrode with an active substance, a conductive flyer, and an ion conductive binder. CONSTITUTION:As an active substance, a redox active high polymer material such as polyacetylene, polypyrrole, or polythiophene is used, and a conductive flyer and an ion conductive high polymer material are added to it. As the conductive flyer, a conductive carbon powder, a carbon substance, a carbon fiber, a metal oxide powder, a metal powder, or a fiber is used, and a fibriform is preferable. As the ion conductive high polymer material, a high polymer matrix which can form an electrolyte salt and a solid solution with the molecular weight more than several thousands oligomers, and a high polymer compound with an ion dissociation radical such as polyethylene oxide as a main chain or a side chain is used. Consequently, the mass energy density is increased, the flexibility is made excellent, and the cell performance is improved. |
