This can be caused by battery misuse, such as overcharging or over-discharging that leads to dendrite formation, impurities and dust during the battery production process. These factors can deteriorate and puncture the separator, causing a micro short circuit. The release of electrical energy leads to a temperature rise. The chemical reactions induced by this temperature rise further enlarge the short circuit path, creating a larger short circuit current. This cumulative and mutually increase the destruction leads to thermal runaway.

      If possible, lithium batteries can be placed in a dedicated fire and explosion-proof box.

✅ Avoid squeezing, colliding the short-circuiting battery to prevent unnecessary losses and safety risks.

✅ Please recharge used batteries promptly to avoid over-discharging during long-term storage, which can damage the battery.

Using water is the most effective way to extinguish the fire. Please use a water-based fire extinguisher. Before extinguishing the fire, you must cut off the power source to avoid electric shock. When using the fire extinguisher, Attack the fire in direction of the wind, lift the fire extinguisher, pull out the safety pin, grasp the handle firmly with your right hand, press down on the handle, and then continuously spray at the base of the flames.

The temperature of a lithium battery fire can reach thousands of Celsius degrees, and the dense smoke while burning is toxic. Wear a smoke mask and high-temperature resistant gloves, and do not directly handle smoking or burning batteries with your bare hands.
