[New Proposal] Solutions for Thermal Runaway Prevention in ESS and EV Batteries

By combining three types of material technologies to achieve overall safety design of the battery pack, we ensure both suppression of heat transfer between cells and reliable sealing of flames and high-temperature gases.

Sekisui Fuller proposes a Fire Containment Solution that contains "heat, flames, and high-temperature gases" during thermal runaway incidents for Energy Storage Systems (ESS) and EV batteries. In recent years, with the expansion of the ESS and EV markets, improving battery safety has become an increasingly important issue. In particular, when addressing thermal runaway, it is crucial not only to prevent heat propagation between cells but also to contain flames, smoke, and high-temperature gases generated from abnormal cells, which is a key point in battery pack design. ▼ To design engineers facing such challenges: - Want to suppress inter-cell fire spread during thermal runaway - Want to reduce the risk of flame and high-temperature gas leakage - Cannot find suitable adhesives for securing fire-resistant materials - Want to improve safety while reducing the number of components - Want to use liquid materials that can be automatically applied Sekisui Fuller addresses these challenges by offering: ✔ Heat propagation suppression ✔ Flame, smoke, and high-temperature gas sealing ✔ Fire-resistant material retention We provide these solutions in a one-stop manner, supporting both safety improvement and increased design flexibility.
