Title:
HEAT INSULATION SHEET OR HEAT INSULATION LAYER
Document Type and Number:
WIPO Patent Application WO/2020/004433
Kind Code:
A1
Abstract:
The present invention provides a heat insulation sheet or a heat insulation layer with which it is possible to inhibit thermal runaway while catering for the need for a higher capacity and a higher density required from a secondary cell, particularly a lithium-ion cell. The present invention provides a heat insulation sheet or heat insulation layer having A) a resin and B) an expandable graphite in which the temperature at which expandability is exhibited is 110-160°C, wherein the heat insulation sheet or heat insulation layer has a thickness of 10 μm to 3 mm.
