▎ 摘　　要

NOVELTY - The structure has a Bismuth-Tellurium-Selenium group thermal conduction material core unit (20) connected with a graphene oxide shell section (30) that is coated on a core unit surface. The shell section comprises graphene oxide of a single layer. USE - Thermoelectric powder core-shell structure for a thermoelectric element (claimed). ADVANTAGE - The structure provides thermal conduction material to coat the graphene oxide on the Bismuth-Tellurium-Selenium group thermoelectric material surface, thus improving thermal stability and preventing material diffusion within thermal conduction material, and hence improving heat resistance and thermal stability of the Bismuth-Tellurium-Selenium group. The structure reduces thermal conductivity and improves thermal stability in a secure manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a thermoelectric powder manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a thermoelectric powder core-shell structure.
