Title:
COMPOSITE PHASE CHANGE MATERIAL FOR MICROWAVE HEATING ENERGY STORAGE AND PREPARATION AND ENERGY STORAGE METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/000585
Kind Code:
A1
Abstract:
A composite phase change material for microwave heating energy storage and a preparation and energy storage method therefor, the composite phase change material having excellent thermal conductivity, a stable heat absorption and release cycle, high latent heat storage density, simple preparation and energy storage operations, and being convenient and reliable. The composite phase change material comprises a uniformly dispersed phase change material and graphene. The mass ratio of the phase change material to the graphene is 1:(0.01-0.05). In the method, according to the mass ratio of the phase change material and the graphene, the phase change material is melted, then graphene is added, and the mixture is fully stirred until same is completely dispersed so as to obtain a composite phase change material after natural cooling. Alternatively, the phase change material and the graphene are mechanically mixed, and then melted and stirred until same are completely dispersed to obtain a composite phase change material. During energy storage, the composite phase change material is subject to microwave irradiation driven by electric energy. The graphene absorbs microwaves to generate heat and conducts same to the phase change material. The electric energy is converted into heat energy by the microwave/graphene action and stored in the composite phase change material.
