Abstract
The present invention relates to a novel secondary battery pack with improved thermal management useful for an all-electric vehicle (EV), a plug-in hybrid vehicle (PHEV), a hybrid vehicle (HEV), or battery packs used for other vehicles batteries, and more particularly, to the use of a specific material for thermally insulating a secondary battery pack and further minimizing the propagation of thermal runaway within a battery pack.
Claims10
A secondary battery pack comprising:
- at least one battery module casing in which is disposed a plurality of battery cells which are electrically connected to one another,
- a silicone rubber syntactic foam comprising a silicone rubber binder and hollow glass beads, and said silicone rubber syntactic foam fills partially or fully the open space of said battery module casing and/or covering partially or totally said battery cells and/or covering partially or totally said module casing, and
- optionally a lid covering the battery module casing,
- wherein the silicone rubber binder in which hollow glass beads are dispersed are obtained by curing a condensation type organopolysiloxane composition and wherein hollow glass beads are hollow borosilicate glass microspheres which have true density ranging from 0.10 gram per cubic centimeter to 0.65 gram per cubic centimeter.
