Title:
GLASS CRYSTAL-BASED ACTIVELY-CONTROLLABLE BAROCALORIC MATERIAL SOLID STATE PHASE TRANSFORMATION HEAT STORAGE AND HEAT RELEASE METHOD, APPARATUS AND USES
Document Type and Number:
WIPO Patent Application WO/2023/133909
Kind Code:
A1
Abstract:
A glass crystal-based actively-controllable barocaloric material solid state phase transformation heat storage and heat release method, an apparatus and uses, belonging to the technical field of solid state phase transformation energy storage. A glass crystal phase is an intermediate metastable state formed in the process of phase transformation from a high-temperature plastic crystal phase to an ordered crystal phase, and can be obtained by means of rapid cooling treatment on a barocaloric material in a high-temperature plastic crystal disordered state. The rapid cooling causes the material in the high-temperature disordered state to be supercooled and frozen, thereby avoiding completely ordered orientation generally occurring at a low temperature. When a micro-pressure is applied to the material, transformation from the glass crystal phase to the ordered crystal phase can be realized, thereby releasing heat. The glass crystal phase has good thermal stability, thereby achieving long-time storage, long-distance transport and controllable release of heat energy.
