A thermal runaway protection system for serially-connected battery cells, comprises a flexible thermal runaway shield ('TRS') and a channel separator. The flexible TRS is configured to be disposed around the serially-connected battery cells. The channel separator is configured to be disposed at a positive cap of one of the serially-connected battery cells. The channel separator comprises a body and a via configured to electrically connect two sides of the channel separator. The body has a raised outer ring with a gap for venting gas during thermal runaway. The raised outer ring is configured to be in contact with the positive cap. The flexible TRS has an opening aligned to the gap of the outer ring.

Thermal runaway shield

A thermal runaway shield ('TRS') having at least one TRS module. The TRS module comprises a first wall, a second wall, and fibers. The first wall has an exterior side and an interior side. The second wall has an exterior side and an interior side. The fibers are disposed on the interior side of the first wall and on the interior side of the second wall. The first wall is coupled to the second wall forming an inner cavity. The at least one of the exterior side of the first wall and the exterior side of the second wall has a shape for conforming to a shape of at least one energy storage device cell.

A battery protection system comprises sleeves, carbon fibers, a case, and liquid. The sleeves are hollow for insertion of battery cells. The carbon fibers are disposed on outer surfaces of the sleeves. The case houses the sleeves and has an inner cavity. The liquid and the carbon fibers are disposed in the inner cavity, where the carbon fibers are exposed to the liquid.

System, method, and apparatus for battery protection

Carbon fiber material and carbon fiber material that is saturated with hydrocarbon solid-liquid phase change material may be used as thermal management materials for providing a thermally conductive interface between a heat source and its housing. Such carbon fiber material may also be used for mechanical isolation of the heat source from its housing. Carbon fibers used in the carbon fiber material may be unidirectionally oriented to provide for low friction, thus optimizing critically controlled friction tolerances. Additionally the carbon fiber material saturated with hydrocarbon solid-liquid phase change material may be used to transfer heat into the an inherently nonconductive medium.
