main types of phase change energy storage materials
How Do Phase Change Materials Work?
How Phase Change Materials Work. At the core of a PCM''s function is the latent heat of fusion—the energy absorbed or released during a change in state, with no change in temperature. When a PCM absorbs heat from its surroundings, it changes from a solid to a liquid, effectively storing this thermal energy in the form of latent heat.
