Title:
BISBTESE-BASED THERMOELECTRIC MATERIAL
Document Type and Number:
WIPO Patent Application WO/2017/041634
Kind Code:
A1
Abstract:
Provided is a BiSbTeSe-based thermoelectric material, the general formula thereof being BimSbnTexSeyMz, wherein m = 0.4-0.6, n = 1.4-1.6, x = 2.7-2.9, y = 0.075-0.3, and z = 0.02-0.15; and M is one or more of S, Si, P, Ge, Sn, Ce, Li, I, Br, Al, Cu, Ag, Yb, Tm, La, Gd and Dy elements. The BiSbTeSe-based thermoelectric material is prepared by the steps such as powder mixing and alloy smelting. The BiSbTeSe-based thermoelectric material of the present invention has the advantages such as a low thermal conductivity and good thermoelectric properties, and extends the application fields of a thermoelectric material.
