Water on a lithium battery fire

Water can worsen a lithium battery fire as it can react with lithium and cause an explosive reaction, which can cause the fire to spread rapidly1. However, it is safe to use water to extinguish the fire of lithium-ion batteries, as they generally contain no solid metallic lithium2. It is important to note that a large amount of water is required to extinguish the fire32. [pdf]
