Wevo-Chemie has developed a range of silicone-based materials for battery modules and packs to prevent thermal runaway propagation.

The thermally conductive gap fillers of the WEVOSIL 260XX FL series are certified UL 94 V-0. The company says its formulation has high heat and flame resistance, lower weight compared to mineral or metal-loaded compounds, and no outgassing during manufacture compared to foams.

“If these tailor-made Wevo solutions are implemented in an early development phase, the overall safety of battery modules can be significantly improved by optimizing thermal management for specific applications and customizing the configuration of thermal, mechanical and electrical barriers,” says the company.
