The prevention of thermal runaway (TR) in lithium-ion batteries is vital as the technology is pushed to its limit of power and energy delivery in applications such as electric vehicles. TR and the resulting fire and explosion have been responsible for several high-profile accidents and product recalls over the past decade.
Flame barrier materials – Thermal runaway protection solutions are rarely a single component or material. Often, raw material combinations are used to leverage the best characteristics from each material, optimize performance, and achieve required compression set and force deflection.
Preventing battery thermal runaway by transferring energy from cells at risk to the battery pack to mitigate the runaway potential. It detects cells at risk of thermal runaway in a battery pack and then transfers the energy from those cells to the battery pack using existing systems like coolant loops, heating elements, and charging circuits.
