Title:
HEAT TRANSFER SUPPRESSION SHEET AND BATTERY PACK
Document Type and Number:
WIPO Patent Application WO/2023/229047
Kind Code:
A1
Abstract:
Provided are: a heat transfer suppression sheet that has such a strength that the shape thereof can be maintained even when a compressive stress is applied to the heat transfer suppression sheet, and that also has a high retention capacity with respect to inorganic particles, thereby being capable of maintaining excellent heat insulation performance; and a battery pack having said heat transfer suppression sheet. A heat transfer suppression sheet (10) has inorganic particles (4) and organic fibers (1). At least some of the organic fibers (1) have a branched structure consisting of a base section (2) and branch sections (3) extending from the base section (2) in, for example, four directions, namely, a direction D1, a direction D2, a direction D3, and a direction D4.
