ABSTRACT:
The battery pack of the invention comprises an outer case, a battery main body disposed within the outer case, and a heat-sensitive current blocking element mounted on the outer surface of the battery main body. On the inner surface of the outer case is provided a press portion for pressing the heat-sensitive current blocking element against the outer surface of the battery main body. In this arrangement, even when the battery pack is given vibration or impact, the heat-sensitive current blocking element can be kept retained in close contact with the outer surface of the battery main body. Accordingly, the heat generated in the battery main body can be rapidly and surely transferred to the heat-sensitive current blocking element, making sure that thermal runaway of the battery is prevented.
