Title:
HEAT-INSULATING SHEET AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2021/131173
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a heat-insulating sheet that is placed between battery cells and can reduce the influence on the adjacent battery cell not only during normal use but also when one battery cell becomes hot. A heat-insulating sheet (11) with silica xerogel (13)-supported glass fiber sheets (12), the heat-insulating sheet (11) being configured so as to contain an infrared absorber (14) constituting 2-15% by weight. Thus, even when one battery cell becomes hot and emits infrared rays, it is possible to prevent the infrared rays from reaching the adjacent battery cell.
