Japanese Patent JP4042187

B2

PROBLEM TO BE SOLVED: To reduce the resistance of a secondary power source and improve the withstand voltage by providing a positive electrode, consisting of a polarizable electrode mainly composed of activated charcoal, a negative electrode consisting of a carbon material impregnated beforehand with lithium ions, and an organic electrolyte containing a lithium salt and a quaternary ammonium salt. SOLUTION: A polarizable electrode obtained by kneading activated charcoal having a specific surface area of 800-3,000 m<2> /g and a conductive carbon black together with a binder is integrated with a current collector by the use of a conductive adhesive to provide a positive electrode body. On the other hand, a negative electrode obtained by storing lithium ion in a lithium storable and releasable carbon material having a spacing of [002] plane of 0.335-0.410 nm by X-ray diffraction measurement through chemical or electrochemical means is integrated with a current collector to provide a negative electrode body. Further, an organic electrolyte containing 0.1-2.0 mol/l of a lithium salt such as LiPF6 and 0.1-2.0 mol/l of a quaternary ammonium salt or quaternary sulfonium salt, and the positive electrode body and negative electrode body are used to provide a secondary power source having high withstand voltage, a large capacity and a low resistance.
