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.

basic information
Sekisui Fuler supports the fire containment of the entire battery pack by combining the following three material technologies. ▼Proposing a three-stage safety design 1. Suppression of heat propagation between cells EV Protect series (flame-retardant foam) Suppresses heat propagation between cells during thermal runaway, reducing the impact on adjacent cells. 2. Sealing of flames, smoke, and high-temperature gases Sekisui fire-resistant sealant Expands approximately three times during a fire to form a ceramic layer, suppressing the leakage of flames, smoke, and heat. 3. Fixing of fire-resistant and insulating materials Sekisui fire-resistant adhesive Exhibits excellent elasticity and durable adhesion under normal conditions, while demonstrating fire-resistant adhesive performance during a fire. It securely holds fire-resistant and insulating materials in place.
