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]

Energy needed to change water from solid to liquid

The amount of heat energy required to change the state of matter of a substance from a solid to a liquid is called the heat of fusion or enthalpy of fusion123. This amount is usually measured in Joules per gram (J/g) or calories per gram (cal/g)1. The heat energy needed to change the substance from solid to liquid at atmospheric pressure is latent heat of fusion, as the temperature remains constant during the process3. [pdf]
