摘要： The present invention discloses a method, device and application of solid-state phase change heat storage and heat release of barocaloric materials based on glassy-crystals and active control, which belongs to the technical field of solid-state phase change energy storage. A glassy-crystal phase is an intermediate metastable state formed in the change process from a high temperature plastic-crystal phase to an ordered crystal phase, which can be obtained by cooling the high temperature plastic-crystal disordered state of the barocaloric materials quickly. Rapid cooling makes the high temperature disordered state of the material supercooled and frozen, thereby avoiding the full oriented order that generally occurs at low temperature. The material is applied with a small pressure, which can achieve the change from the glassy-crystal phase to the ordered crystal phase, thereby achieving heat release. The glassy-crystal phase has good thermal stability, thereby achieving long-term storage, long-distance transportation and controllable release of heat energy.
