Copper-silver-based chalcogenide thermoelectric material and preparation and application thereof
The invention relates to a copper-silver-based chalcogenide thermoelectric material and preparation and application thereof. The chemical general formula of the thermoelectric material is (Cu1-xAgx)2(Te1-ySy), wherein the value of x is 0.16 to 0.24, and the value of y is 0.16 to 0.24. Compared with the prior art, the thermoelectric performance of (Cu1-xAgx)2(Te1-ySy) is excellent, the ZT of part of samples can reach 2.0 at 1000K, and the Cu1-xAgx2(Te1-ySy) is suitable for the application scene of a medium-high temperature area. In addition, the Cu1-xAgx2(Te1-ySy) copper-silver-based chalcogenide thermoelectric material has a relatively high Seebeck coefficient and extremely low thermal conductivity.
本发明涉及一种铜银基硫属化物热电材料及其制备和应用，该热电材料的化学通式为(Cu1‑xAgx)2(Te1‑ySy)，x的值为0.16～0.24，y的值为0.16～0.24。与现有技术相比，本发明的(Cu1‑xAgx)2(Te1‑ySy)的热电性能优异，部分样品的ZT在1000K时可达到2.0，适用于中高温区的应用场景。而且，所述(Cu1‑xAgx)2(Te1‑ySy)铜银基硫属化物热电材料具有较高的塞贝克系数以及极低的热导率。
