摘要 |
A coin-shaped lithium battery is disclosed. The coin-shaped lithium battery comprises a battery can containing therein an anode pellet composed of lithium or lithium alloy and a cathode pellet which are arranged to face each other with a separator provided between the pellets. At least one of the anode pellet and the cathode pellet has its central part swollen to form a curved surface. The battery can is elastically deformed to be aligned with the curved surface. In the coin-shaped lithium battery, total height of the anode pellet and the cathode pellet in outer rim part is smaller than total height in central part by 4 to 12%.
