The application of special vacuum insulation panels (VIP) in battery thermal management

Insulation materials are indispensable key materials in battery thermal management systems.

Special vacuum insulation panels (VIP) have shown promising application prospects in enhancing the performance of battery systems due to their outstanding insulation and fire resistance properties. This paper systematically introduces the main performance indicators of metal VIP and ultra-thin VIP for the first time, conducts tests and analyses on heat insulation performance and dynamic heat transfer characteristics, and makes comparisons with current aerogel felt products. It is used for battery pack insulation, significantly improving the low-temperature environmental adaptability and endurance of battery packs, as well as suppressing the diffusion of battery thermal runaway. At the same time, it has a high cost performance. The results show that the new type of special vacuum insulation products have more advantages in the integrated design of heat dissipation, insulation and fire prevention for batteries and energy storage systems.
