Title:
HEAT TRANSFER SUPPRESSION SHEET AND BATTERY PACK
Document Type and Number:
WIPO Patent Application WO/2024/004968
Kind Code:
A1
Abstract:
The present invention provides: a heat transfer suppression sheet which has excellent thermal insulation properties and prevents ingress of water, thereby being capable of preventing ignition due to a short circuit between battery cells, and the like, and which is preferably capable of preventing a decrease in the thermal insulation properties due to ingress of an electrolyte solution; and a battery pack which comprises this heat transfer suppression sheet. A heat transfer suppression sheet (10) being interposed between a plurality of battery cells comprises: at least one kind of fibers (glass fibers (1)) which are selected from among inorganic fibers and organic fibers; and a liquid repellent substance (2) which has a surface tension that is lower than the surface tension of water.
