For new energy vehicles, the battery cell is the source of kinetic energy for pure electric vehicles. The safety hazard of the battery cell directly affects the safety performance of the car. When the battery cell is working, it will generate a certain amount of heat, which can be generated at different temperatures. A certain thermal expansion and contraction effect will cause a certain expansion of the battery cells, and long-term friction between the battery cells may cause damage to the battery cells and cause the rechargeable battery to be invalid, and even uncontrollable in severe cases.

The silicone foam produced by our company can be used as a better solution material for expansion of soft-packed cells, delaying the spread of thermal runaway of cells, cushioning of square/soft-packed cells, and potting of cylindrical cells.

Silicone foam has good compression deformation resistance and low stress relaxation performance. With its high reduction and reduction characteristics, the battery can avoid deformation caused by thermal expansion and contraction of the rechargeable battery during charging and discharging, and it also has excellent temperature resistance. Performance (-40~+220°C) and flame retardancy (reaching the requirements of UL94 V0 fire rating).
