Energy Storage Systems (ESS) using lithium-ion batteries are highly susceptible to thermal runaway, a phenomenon in which temperatures rise rapidly during a fire, potentially leading to cascading failures and secondary explosions.
Battery Cell Thermal Runaway
Internal short circuits, overcharging, mechanical damage, or external impacts can cause battery cell temperatures to rise rapidly to uncontrollable levels.
Heat Transfer Between Racks
Intense Heat and flames generated by a single battery module can rapidly propagate to adjacent battery racks and surrounding equipment, increasing the risk of large-scale fire spread.
Large-Scale Fire Propagation
In densely packed battery installations, heat and flame propagation can exceed the limits of fire compartmentation, allowing the fire to spread throughout the facility.
SFEXTECH’s solutions are preventive fire protection systems designed to prevent thermal runaway propagation between ESS battery cells and racks and inhibit flame spread. They help ensure compliance with electrical safety standards and strengthen proactive workplace safety and health management systems.
Based on advanced high-performance non-combustible material technology, SFEXTECH isolates extreme heat and flames generated during battery thermal runaway, preventing the spread of fire into large-scale incidents.
Prevention of Thermal Runaway Propagation with SFEX Thermal Barrier
SFEX Thermal Barrier is a specialized fire-resistant barrier designed to provide both non-combustible and thermal barrier performance. It helps prevent heat transfer between batteries while blocking the propagation of heat and flames to adjacent fire compartments during thermal runaway or fire events.
Utilizing advanced multi-layer engineering based on FR Board, a high-performance non-combustible reinforced plastic, it effectively isolates the extreme heat and flames generated during battery thermal runaway, helping prevent thermal propagation and secondary ignition in adjacent batteries.
Engineered with an advanced multi-layer structure, it provides both fire barrier and thermal insulation performance while ensuring superior tensile strength, making it suitable for a wide range of installation environments.
In addition to serving as a fire-rated partition between battery racks to block heat transfer, it can also be installed as an overhead fire barrier to protect cable systems located above the racks.
