摘要： PROBLEM TO BE SOLVED: To provide a secondary battery in which a liquid electrolyte is used and which has an excellent preservation property. SOLUTION: The secondary battery is provided with a cathode, an anode and liquid electrolyte, and a cathode active substance and an anode active substance are composed of the same compound. Since the cathode and anode active substances are of the identical compound to form a symmetric electrode structure, electrode potential differences before charging or when discharging are made equal, and as a result, the deterioration of the electrolyte is effectively controlled and the preservation property is improved.
