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 closely thermally coupled to the battery. The heat absorber includes heat absorbing material preferably exhibiting an endothermic phase change at a temperature T1 below that produced by the battery.
