Document Type and Number:
WIPO Patent Application WO/2023/229043
Kind Code:
A1
Abstract:
Provided are: a heat transfer suppression sheet having enough strength to maintain the shape thereof even when an impact or pressing force is applied thereto, thus making it possible to suppress powder falling and maintain excellent heat insulation performance; and a battery pack having said heat transfer suppression sheet. The heat transfer suppression sheet (10) has inorganic particles (4) and organic fibers (1). In addition, a first region (2) having a streaky fiber bundle (7) composed of a plurality of organic fibers (1), and a second region (3) in which the fiber bundle (7) is not present are formed on the surface of the heat transfer suppression sheet (10).
