HEAT TRANSFER SUPPRESSION SHEET AND BATTERY PACK
Document Type and Number:
WIPO Patent Application WO/2023/229042
Kind Code:
A1
Abstract:
Provided are: a heat transfer suppression sheet that has a degree of strength, enabling the shape of the heat transfer suppression sheet to be maintained, and that has a high retention capacity with respect to inorganic particles even when compression stress is applied to the heat transfer suppression sheet, whereby the heat transfer suppression sheet can maintain superior heat insulation performance; and a battery pack having this heat transfer suppression sheet. A heat transfer suppression sheet (10) has a matrix (14) including inorganic particles (4), and organic fibers (1) three-dimensionally oriented in the matrix (14). The organic fibers (1) have fused parts (5) of which at least part of the surfaces are covered, and the organic fibers (1) are fused to each other by the fused parts (5).
