Title:
HEAT INSULATION SHEET FOR ASSEMBLED BATTERIES AND ASSEMBLED BATTERY
Document Type and Number:
WIPO Patent Application WO/2021/039844
Kind Code:
A1
Abstract:
Provided are: a heat insulation sheet for assembled batteries, which is capable of exhibiting excellent heat insulation properties over a wide temperature range from normal usage temperatures of the battery up to a high temperature of 500°C or higher, and preferably, capable of maintaining the excellent heat insulation properties even in the case where the heat insulation sheet is subjected to an increased level of compressive stress; and an assembled battery in which such a heat insulation sheet is interposed between battery cells. A heat insulation sheet (10) according to the present invention is to be used in an assembled battery in which a plurality of battery cells are connected either in series or in parallel, so as to be interposed between the battery cells, wherein the sheet comprises first particles (21) composed of silica nanoparticles and second particles (22) composed of a metal oxide, and the content of the first particles (21) is 60-95 mass% of the total mass of the first particles (21) and the second particles (22).
