Title:
HEAT FLOW REGULATING COVER FOR AN ELECTRICAL STORAGE CELL
Document Type and Number:
WIPO Patent Application WO2004081686
Kind Code:
A3
Abstract:
A temperature regulating cover (34, 36, 38) for use on an electrical energy storage cell (30) that may produce heat at a hot spot during a short circuit condition. The cover includes a first layer (34, 36) of thermally conductive material that is shaped to conform to an outer surface (31) 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 (38) of thermally insulating material that is shaped to conform to an outer surface (35) of the first layer and that retards heat flow to an outer surface (39) of the second layer.
