PURPOSE: To provide a small, lightweight battery having long-term reliability, high safety, a high battery characteristic, and high workability by forming a composite positive electrode, an electrolyte, and a composite negative electrode with ion conducting polymer compounds constituted of organic compounds satisfying specific structural formulas. CONSTITUTION: Ion conducting polymer compounds are constituted of organic compounds satisfying one of structural formulas I-III, ionic compounds, organic compounds dissolving the ionic compounds, and nylon grains having the average grain size of 15μm or below. A composite positive electrode, an electrolyte, and a composite negative electrode are formed with the ion conducting polymer compounds. When they are assembled into a battery, the battery has long-term reliability because of no liquid leak to the outside, and it is shut down by the increased resistance of fused nylon grains at the time of a temperature rise. The small, lightweight battery having high safety against an abnormal current, a high battery characteristic, and high workability is obtained. In the formulas, R1 -R3 indicate hydrogen atom or the lower alkyl group having the carbon number of 1 or above, m>=1, n>=0, and n/m=0-S. |
