PURPOSE: To provide an organic electrolyte battery which has a large capacity even at low temperature and has little capacity decrease against heavy load discharge by using an insoluble and infusible base body having a polyance skeletal structure for electrode active material, and using organic electrolyte utilizing specific mixed solvent as electrolyte solvent. CONSTITUTION: An organic electrolyte battery is provided with a positive electrode 1, a negative electrode 2, and the aprotic organic solvent of lithium salt as electrolyte 4. The negative electrode 2 is the heat treated substance of an aromatic condensation polymer, and an insoluble and infusible base body (PAS) having a polyacene skeletal structure of which hydrogen atom/carbon atom atomic ratio (H/C) is 0.5 to 0.05 and an adsorption gas amount at a nitrogen adsorption thickness of 10A obtained from a nitrogen adsorption isotherm is 100cc/g or less. The mixed solvent of cyclic ester carbonate, chain ester carbonate, and chain ester is contained as electrolyte solvent. |
