Piercing a lithium-ion battery can lead to a serious fire in some cases. Potent electrolytes can leak through the hole, often creating chemical reactions that release heat. This heat can then damage other battery cells, creating a chain reaction of damage. This process is called thermal runaway1. If the battery is charged or even partially charged, puncturing it will result in a short circuit. This short circuit will cause the battery to discharge all at once, which happens at an enormous current2. Piercing nozzles are designed to puncture the battery box in an effort to deliver large quantities of water inside the box to cool the battery cells, but this solution is dangerous due to the electrocution hazard3. Firefighters use piercing nozzles to deliver water directly to the cells of a burning battery pack4.
