Title:
HYDRATED SALT THERMOCHEMICAL HEAT STORAGE COMPOSITE MATERIAL, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/159996
Kind Code:
A1
Abstract:
A hydrated salt thermochemical heat storage composite material, a preparation method therefor and an application thereof. A hydrated salt thermochemical energy storage composite material having excellent thermochemical heat storage performance, good thermal conductivity and compression resistance is obtained by compounding a hydrated salt with a highly thermal conductive material and a reinforcing material. The composite material can be filled in a battery module, and when batteries go into thermal runaway due to electrical abuse, mechanical abuse and thermal abuse, the thermal runaway of the batteries can be alleviated and the spread of the thermal runaway of the batteries can be restrained. In addition, a thermochemical heat storage principle can be used in battery thermal runaway protection, and a simple model for describing the thermochemical heat storage process of the material is constructed, so as to quickly and reasonably estimate the temperatures of the batteries and optimize the amount of the composite material in the module.
