Abstract
A temperature regulating cover for use on an electrical energy storage cell that may produce heat at a hot spot during a short circuit condition. The cover includes a first layer of thermally conductive material that is shaped to conform to an outer surface of the electrical energy storage cell and spreads heat from the hot spot over surface area that is larger than the hot spot. The cover also includes a second layer of thermally insulating material that is shaped to conform to an outer surface of the first layer and that retards heat flow to an outer surface of the second layer.
