Problems solved by technology

[0006] At present, some battery thermal management devices using phase change materials have been proposed at home and abroad, but there are many disadvantages. The phase change materials in the phase change cooling devices proposed by existing patents are basically functional materials, which are prone to fracture, deformation, After heating, the phase change material melts and easily leaks, especially in the state of movement and vibration, and the battery pole piece is easy to fall off, causing structural damage and threatening the safety of the battery
