In case of thermal runaway, insulation materialcan delay heat diffusion and prevent or delay accidents。

When the electric cell is out of control, the flame retardant material can delay the spread of the fire and increase the escape time due to the flame retardant effect

The buffer material can absorb the expansion stress of the battery, extend the cycle life of the battery, and absorb the tolerance of the module to play a role in positioning. Because the power battery will change in volume due to the material in the electrode deembedding and embedding, thermal expansion and cold contraction and other factors, shockproof materials Can help to achieve constant pressure between cells.
