Document Type and Number:
WIPO Patent Application WO/2024/060114
Kind Code:
A1
Abstract:
An Mg-Sb-based thermoelectric device comprising a high-entropy thermoelectric interface material, and a preparation method. The thermoelectric device comprises a thermoelectric conversion material and a thermoelectric interface material. The thermoelectric interface material is compounded onto at least part of the surface of the thermoelectric conversion material; and the thermoelectric interface material comprises the following chemical general formula: FeaTibCrcMndMge, where a = 0.5-1.5; b = 0.5-1.5; c = 0.5-1.5; d = 0.5-1.5; and e = 0.5-1.5. The FeaTibCrcMndMge/TEcM contact interface not only has superior comprehensive performance after synthesis, but also still has a high shear strength (> 30 MPa) and a low contact resistance (< 10 μΩ*cm2) after 15 days of service at 400ºC.
