A common approach to thermal storage is to use what is known as a phase change material (PCM), where input heat melts the material and its phase change — from solid to liquid — stores energy. When the PCM is cooled back down below its melting point, it turns back into a solid, at which point the stored energy is released as heat.
Here, emphasis has been laid on application of such materials (i.e. Phase change materials). An important method of thermal management of battery systems is the application of phase change materials in it.
