Why do lithium-ion batteries catch fire? Lithium-ion battery cells combine a flammable electrolyte with significant stored energy, and if a lithium-ion battery cell creates more heat than it can effectively disperse, it can lead to a rapid uncontrolled release of heat energy, known as ‘thermal runaway’, that can result in a fire or explosion.
When a lithium-ion battery fire breaks out, the damage can be extensive. These fires are not only intense, they are also long-lasting and potentially toxic. What causes these fires? Most electric vehicles humming along Australian roads are packed with lithium-ion batteries.
Lithium-ion battery fires are happening more often. Here’s how to prevent them | CNN Business Lithium-ion battery fires are happening more often.
Water also conducts electricity, which means spraying it on a battery fire could lead to electrical shocks or short-circuits if the battery is not electrically isolated. Globally, numerous solutions have been proposed for extinguishing lithium-ion battery fires.
Mechanical injury is another leading cause of lithium battery fires and explosions. Physical damage to a battery, whether from crushing, puncturing, or bending, can compromise its structural integrity.
In case of a lithium-ion battery fire, evacuate the area, use a Class D fire extinguisher only, and call the fire department. It is recommended that you never reuse or recharge the damaged battery because this is very dangerous. Besides this, you can opt for the following measures.
