  • Patent number: 6451474
    Abstract: A battery pack that reduces thickness and lightens weight as required for battery power sources of portable electronic equipment. A battery pack is constituted by accommodating a battery and battery protection device between a top case and bottom case forming a pack case. Since the battery is formed accommodated within an external casing wherein positive and negative electrode plates are formed by laminated sheet, reduced thickness and reduced weight of battery pack can be achieved. Also, since the face of bottom case opposite the battery is formed as a resiliently deformable face which is formed of small thickness, when expansion takes place such that the thickness of the battery as a whole increases, resiliently deformable face deforms maintaining a planar condition by resilient deformation, so that there is no possibility of an adverse effect on the equipment due to drum-shaped swelling being produced in battery pack, by such swelling.
