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.
Claims21
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 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 said silicone rubber syntactic foam is obtained by curing an addition curing type organopolysiloxane composition X, and wherein the addition curing type organopolysiloxane composition X comprises:
- a) at least one organopolysiloxane A having at least two alkenyl groups bonded to silicon per molecule, said alkenyl groups each containing from 2 to 14 carbon atoms,
- b) at least one silicon compound B having at least two hydrogen atoms bonded to silicon per molecule,
- c) hollow glass beads D, and
- d) a hydrosilylation catalyst C.
