Title:
ANTIMONY-TELLURIDE THERMOELECTRIC MATERIAL HAVING SHEET-SHAPED STRUCTURE, AND METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2020/096302
Kind Code:
A1
Abstract:
The present invention relates to a thermoelectric antimony-telluride (Sb2Te3) material having a sheet-shaped structure, and a method for preparing same, wherein by controlling reaction conditions during the process of synthesizing antimony-telluride (Sb2Te3), the method can synthesize a sheet-shaped structure having an orientation for growth in a direction perpendicular to the c-axis of crystallographic direction, and can further enable an arrangement in a direction that reduces thermal conductivity and increases thermoelectric conversion efficiency. The method for preparing a thermoelectric antimony-telluride material having a sheet-shaped structure according to the present invention comprises: a dissolution step in which an antimony (Sb) precursor and a tellurium (Te) precursor are each dissolved in organic solvents, thereby producing solutions; a mixing step in which the antimony (Sb) solution and the tellurium (Te) solution are mixed together, and then mixed with a basic solution, thereby producing a solution mixture; and a synthesis step in which the solution mixture is placed in a solvothermal reactor and subjected to a synthesis.
