PROBLEM TO BE SOLVED: To provide a battery improved in durability by enhancing sealing capability and heat dissipation capability of the battery covered with a laminate film. SOLUTION: This laminate-armored flat battery is characterized by fixing thermally welding parts for catching an electrode terminal lead by pinching means formed on the upper and lower sides thereof. By fixing them with the pinching means, the sealing capability of the thermally welding part is improved, strength of an electrode can be increased by an anchor effect, and the battery service life can be extended. The battery is excellent as an battery for an automobile expected to be used for a long time in a vibrating condition, and required to feed large-capacity power. COPYRIGHT: (C)2004,JPO |
