PURPOSE:To provide a battery which has excellent cycle life and in which no liquid leakage or bursting occurs by using a negative electrode base composed of at least one compound selected from among tungsten oxide, tantalum oxide and titanium oxide. CONSTITUTION:A negative electrode is prepared from an electrode base composed of at least one compound selected from among tungsten oxide, tantalum oxide and titanium oxide. These oxides of transition metals are used in the form of a film prepared by electrochemically subjecting the metal to anodic oxidation. A battery is assembled by using the negative electrode, a positive electrode made of carbon and organic electrolyte. In this battery, only slight capacity decrease is caused by repeated charging and discharging and no damage such as liquid leakage or bursting occurs. Therefore this battery has high quality. |
