THERMAL ENERGY STORAGE WITH PHASE CHANGE MATERIALS HAVING AN ADJUSTABLE TRANSITION TEMPERATURE

This disclosure provides systems, methods, and apparatus related to thermal energy storage with phase change materials having an adjustable transition temperature. In one aspect, a method includes providing a device. The devices includes a phase change material, a salt dissolved in the phase change material, and an anode and a cathode disposed in the phase change material. The phase change material changes from a solid to a liquid at a first temperature when the salt is dissolved in the phase change material. A voltage is applied to the anode and the cathode to substantially remove the salt from the phase change material. The phase change material changes from the solid to the liquid at a second temperature when the salt is substantially removed from the phase change material, with the first temperature being a lower temperature than the second temperature.
