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.
Claims25
A silicone rubber syntactic foam comprising a silicone rubber binder and hollow glass beads,
- wherein said silicone rubber syntactic foam is obtained by curing an addition curing type organopolysiloxane composition X,
- wherein the addition curing type organopolysiloxane composition X comprising
