  • Publication number: 20050208347
    Abstract: This invention concerns a secondary battery which ensures safety with a simple structure and promotes exaltation of the service life of battery. This secondary battery is formed by interposing a nonaqueous electrolyte between the positive pole and the negative pole and connecting a group of diodes between the positive pole terminal forming the positive pole and the negative pole terminal forming the negative pole in the direction in which the forward direction voltage is applied. Owing to this structure, the secondary battery is enabled to possess the function of protecting the battery from overcharging and overdischarging even when the voltage is abnormally lowered during the course of discharging.
