Document Type and Number:
WIPO Patent Application WO/2024/060115
Kind Code:
A1
Abstract:
A thermoelectric device containing a protective layer and a manufacturing method therefor. The thermoelectric device comprises a thermoelectric conversion material and a thermoelectric interface material; the thermoelectric interface material is compounded to at least a portion of the surface of the thermoelectric conversion material; at least a portion of the surface of the thermoelectric interface material is compounded with a protective layer; and the protective layer comprises magnesium or a magnesium alloy. The Mg3Sb2-based thermoelectric material protected by a coating has excellent stability, and has a small internal resistance change rate and Seebeck coefficient change rate after 30 days of service at 400°C. After extreme testing at a high current density, the material has a small internal resistance change rate.
