Title:
HEAT TRANSFER SUPPRESSION SHEET AND BATTERY PACK
Document Type and Number:
WIPO Patent Application WO/2023/120544
Kind Code:
A1
Abstract:
In the present invention, uniform heat insulation and heat dissipation are obtained, and if thermal runaway occurs in a battery cell, heat is blocked between adjacent battery cells, and the heat generated by the battery cells is quickly dissipated. A heat transfer suppression sheet (10) includes: uniformly dispersed inorganic particles (21); first inorganic fibers (23) that are uniformly dispersed and oriented in one direction parallel to the main surfaces (10a, 10b) of the sheet; and second inorganic fibers (24) that intertwine with the first inorganic fibers (23) to form a (3)-dimensional web structure.
