So appropriate gas detection and venting systems must be considered as practical measures and as required by code. Also, understand that it may lead to an explosion as batteries can propagate between cells even if not on fire. If appropriate, use a fire suppression design specifically designed for this application. The best way to manage a lithium-ion (Li-ion) battery failure, either fire or explosion, is to address the hazards holistically. When you address the fire hazard, it can make the explosion hazard worse, and addressing the explosion hazard can make the fire hazard worse. So, the unfortunate outcome of thermal runaway is either fire or gas production. When LIB fails, certain LIB technologies catch fire some technologies do not catch fire but off the gas, a potentially explosive mixture of gasses such as Hydrogen. What we want to manage/ mitigate is the failure propagation between cells. Ergo, you should ensure that the battery is being charged away from other fuels and exposed in a safe place that cannot ignite these other fuels. It won’t even be controlled by unplugging the battery. Additionally, you may not know when this runaway started, so it could be a reaction that takes place for a long time before you become aware of it. For example, after thermal runaway starts, the process will not be able to be stopped. If or when the case around the battery begins to fail, the flammable and toxic gases within the cell are released. In addition, thermal runaway can happen if a battery is exposed to abused conditions such as high temperatures, physical abuse or if it is charged improperly.ĭuring the thermal runaway of a battery, the chain reaction vaporizes the organic electrolyte and pressurizes the cell casing. This process can occur within the battery if it becomes too hot, and it causes a chain reaction that can ultimately lead to a fire. One of the main reasons why lithium-ion batteries can catch fire or fail is due to thermal runaway. Generally referred to as “thermal runaway.” This can occur in Energy Storage Systems, ESS, often comprised of Lithium-Ion Batteries. Maybe the question should be, “should we put out a Lithium-Ion battery fire”? LIB (lithium-ion battery) failure is a thermal management problem that can lead to a fire.
