Description

technical field

[0001] The present invention relates to a kind of cobalt antimonide (CoSb 3 ) thermoelectric element matching alloy electrode and one-step connection process, more precisely, the present invention relates to the electrode selection of cobalt antimonide-based thermoelectric device and the connection process between electrode and thermoelectric material, which belongs to the technical field of electrode selection and preparation of thermoelectric components . Background technique

[0002] Thermoelectric material is a functional material that converts thermal energy and electrical energy. It uses its own Seebeck effect to directly convert thermal energy into electrical energy. Thermoelectric power generation components made of thermoelectric materials do not require mechanical moving parts and do not undergo chemical reactions. , has the advantages of long life, high reliability, and no pollution to the environment. In addition to being used in the aerospace fi...
