摘要： PURPOSE:To make high current density discharge possible by arranging solid electrolyte on surfaces and in pores of electrode active material. CONSTITUTION:Solid electrolyte is placed on surfaces and in pores of electrode active material. For example, polyethylene oxide and LiBF4 are dissolved in acetonitrile solvent, and gelled polyacetylene is immersed overnight in this solution. Refrigerant and polyacetylene are separated, and solvent in the polyacetylene is removed in a vacuum and solid electrolyte is held in the fine pores of polyacetylene 2 and 4. Polyacetylene obtained is pressed to make film. Solvent of solution prepared by dissolving polyethylene oxide and LiBF4 in acetonitrile solvent is vaporized to prepare 0.2-0.3mm. thick solid electrolyte 3. Solid electrolyte 3 is combined with polyacetylene electrodes 2 and 4 to form a battery.

摘要： PURPOSE:To obtain a secondary battery having long life by arranging a metal electrode apart from positive and negative electrodes in a polymer battery and forming a circuit by which positive electrode and negative electrode are separately discharged. CONSTITUTION:A battery 1 uses polyacetylene in a positive electrode 1 and a negative electrode 3, and acetonitrile solution of (C2H5)4NBF4 as electrolyte. A platinum wire 4 is arranged in the battery 1 to form a circuit by which positive electrode and platinum wire, and negative electrode and platinum wire are separately discharged. For example, positive electrode and negative electrode are completely discharged once every 10 charge-discharge cycles by using this circuit. Imbalance in doping ratio of positive electrode and negative electrode is suppressed and deterioration of double bond is decreased and charge-discharge cycle life is remarkably increased.
