Abstract
A method and apparatus for containing heat generated by a battery to reduce the amplitude of a temperature excursion to enhance safety in temperature critical applications, such as in implantable medical devices. The apparatus employs a heat absorber (38) closely thermally coupled to the battery (30). The heat absorber includes heat-absorbing material preferably exhibiting an endothermic phase change at a temperature below that produced by the battery.
