Phase Change Materials & Devices
Phase change material (PCM) based thermal energy storage (TES) has many current and potential applications such as the heating and cooling of buildings, battery and electronics thermal management, thermal textiles, dry cooling of power plants and transportation of pharmaceutical and medical supplies.
Tuning of the transition temperature of a material using an external stimulus such as pressure or an electric field is a non-trivial task as the magnitude of the required stimulus is typically very high. To circumvent this problem here we developed the dynamic tunability of the transition temperature of a PCM using ions.
