In recent years, there have been significant advancements in the research of thermal insulation materials for LIB modules. Aerogel is often used as a thermal insulation layer, often combined with PCM, metal, fiber, and other materials.
The thermal spreading interval between the thermal runaway battery and the neighboring batteries in the module is increased to an infinite length, and only the thermal runaway battery shows the phenomenon of spraying valve such as fire and smoke. It is expected to have a guidance for the design of thermal insulation in lithium-ion battery modules.
Presently, numerous domestic battery manufacturers have incorporated aerogel thermal insulation materials into their production processes, with leading companies like Ningde Times, Chongchuang Materials, and Guoxuan Hi-Tech already adopting this technology.
The thermal spread suppression experiment was carried out by using the control variable method, and the influence of different material insulation layers on the thermal spread inhibition performance of lithium-ion battery module was studied.
