To ensure that the cell expansion and contraction during normal charging and discharging of the batter y can effectively store and absorb the pressure of the contraction, and at the same time prevent the heat from spreading and spreading during thermal runaway. Hongchi has specially designed the MSD400-TC series heat insulation and buffering silicone foam for it. During normal operation, it maintains good flexibility and compressibility, enabling it to have the functions of buffering, absorbing pressure, maintaining insulation, and filling gaps; during thermal runaway, it can quickly for m a ceramic structure to achieve excellent heat insulation, blocking the spread and expansion of heat, and delaying the fire of the batter y.
