Description

technical field

[0001] The invention relates to an energy storage system based on a single thermal-electric cell. Background technique

[0002] Thermoelectric materials are functional materials that can convert thermal energy and electrical energy. The Seebeck effect discovered in 1823 and the Peltier effect discovered in 1834 provide a theoretical basis for the application of thermoelectric energy converters and thermoelectric refrigeration. With increasing interest in space exploration, advances in medical physics, and increasingly difficult resource exploration and exploration activities on Earth, there is a need to develop a class of power systems that can self-supply and leave unattended, and thermoelectric power generation is particularly suitable for these applications.

[0003] The use of natural temperature difference and industrial waste heat can be used for thermoelectric power generation. It can use the non-polluting energy existing in nature and has good compreh...
