  • BATTERY PACK AND BATTERY-EQUIPPED DEVICE
    Publication number: 20100255359
    Abstract: The invention provides a battery pack and a battery-equipped device in which, even if a battery experiences an abnormal event to cause thermal runaway, and generates heat, temperature increase in the battery pack and batteries except for the battery which experienced the abnormal event can be prevented. For this purpose, a heat absorbing member 4 is arranged in space inside a battery pack 1 between a casing 2 and batteries 3. Even if one of the batteries 3 experiences thermal runaway, the heat absorbing member 4 absorbs heat generated by the battery 3, thereby preventing the thermal runaway from occurring in the other batteries 3.
