Document Type and Number:
WIPO Patent Application WO/2023/112972
Kind Code:
A1
Abstract:
Provided are: a heat transfer suppressing sheet capable of maintaining the shape thereof even when the heat transfer suppressing sheet is pressed due to the expansion of a battery cell and thereby suppressing deterioration of thermal insulation properties; a method for manufacturing the same; and a battery pack having said heat transfer suppressing sheet. The heat transfer suppressing sheet contains first inorganic particles (1), a resin binder (6), and organic fibers (3), and the glass transition temperature of the organic fibers (3) is higher than the glass transition temperature of the resin binder (6). Further, at least some of the organic fibers (3) are fused together to form a three-dimensional skeleton (8). The resin binder (9) is fused with part of the skeleton (8) and at least part of the first inorganic particles (1) to cause at least part of the first inorganic particles (1) to adhere to the skeleton (8).
