Nano-Silica Composite Thermal Insulation Board
- Nano-silica composite thermal insulation board is designed for thermal protection between cells in power batteries and energy storage batteries.
- It helps block heat transfer from a thermal runaway cell to adjacent cells, suppressing thermal propagation and reducing the risk of chain-reaction thermal runaway, thereby improving overall battery system safety.
