Title:
FUNCTIONAL HEAT INSULATION DEVICE FOR LITHIUM BATTERY
Document Type and Number:
WIPO Patent Application WO/2020/024499
Kind Code:
A1
Abstract:
A functional heat insulation device (2) for a lithium battery, comprising a functional material. The functional material is a material having a fire extinguishing function and a heat absorption and cooling function, and the functional heat insulation device (2) is fixedly mounted on a side surface of a lithium ion cell (1). Compared with the existing heat insulation cotton technology, the functional heat insulation device can more effectively prevent a heat transfer phenomenon between lithium ion cells, reduce the energy produced by lithium battery deflagration, and avoid the occurrence of lithium ion cell ignition, and thus effectively reducing a chain reaction caused by lithium ion battery ignition or explosion, and improving a safety performance of a lithium ion battery to a large extent.
