Title:
MAGNESIUM-ANTIMONY-BASED THERMOELECTRIC ELEMENT, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/168531
Kind Code:
A1
Abstract:
Provided by the present invention is a magnesium-antimony-based thermoelectric element, a preparation method therefor, and an application thereof. The magnesium-antimony-based thermoelectric element comprises: a substrate layer made of a magnesium-antimony-based thermoelectric material that is located at the center of the thermoelectric element, transitional layers that are attached to two surfaces of the substrate layer, and two electrode layers that are respectively attached to surfaces of the two transitional layers; the material of the transitional layers is a magnesium-copper alloy and/or a magnesium-aluminum alloy, and the material of the electrode layers is copper. The transitional layers and the electrode layers which are developed in the present invention and which are applicable to a magnesium-antimony-based thermoelectric material have great significance and prospects in application; meanwhile, the electrode layers provide the opportunity for a magnesium-antimony-based thermoelectric material to enter the market and make commercialization possible. Compared with existing bismuth telluride thermoelectric devices on the market, the thermoelectric device prepared according to the present invention has lower costs, may simultaneously save the rare element tellurium, and is beneficial in saving energy and protecting the environment.
