PROBLEM TO BE SOLVED: To provide an organic electrolyte battery which has excellent cycle characteristic and a small lowering in the capacity at low temperatures. SOLUTION: In an organic electrolyte battery equipped with a positive electrode 1, a negative electrode 2, and an aprotic organic solvent of a lithium salt as the electrolyte, the negative electrode 2 includes an infusible/insoluble substrate which is heat-treated aromatic group condensation polymer and has a polacene-derived skeletal structure wherein an atomic ratio of hydrogen atoms/ carbon atoms is 0.50 to 0.05, and the electrolyte solvent is a mixed solvent of ethylene carbonate, diethyl carbonate, and propylene carbonate, wherein the propylene carbonate accounts for not more than 20% and not less than 3% by a weight ratio to the total and the ratio of the ethylene carbonate to the diethyl carbonate is 70/30 to 30/70. |
