Solar energy storing and electricity generating sodium-sulfur cell

Abstract

The invention relates to a solar energy storing and electricity generating sodium-sulfur cell which consists of a photothermal collection system, a photoelectric and thermoelectric conversion system and an energy storing and electricity generating system and is characterized in that a universal lens (1), a focusing ball (2) and a photothermal collector (8) are connected on a case; an optical fiber sensor (5) is connected with a photoelectric converter (12) in the case; a heat pipe (3) is respectively connected with a thermoelectric converter (13) and a heating tank (14); a sodium-sulfur cell (15) is connected in the heating tank (14); a lead (6) is connected with each epitaxial electrode (7) to the output of a rectifier (10); and an external network interface (4) is arranged outside the case (9) and is used as an emergency charging port. The invention has the characteristics that solar energy optothermal not only can be used for generating electricity but also can be used for insulating the heating tank, thereby fully performing the functions of the sodium-sulfur cell. The sodium-sulfur cell has the characteristics of large energy and power density, quick charging time, high charging and discharging efficiency, long service life, no pollution of raw materials of cells, no limitation of fields, convenient maintenance and the like, so the sodium-sulfur cell can be used as an advanced energy storing and electricity generating power source to improve the utilization efficiency of the whole power industry; and because a method of supplying a heat source following the sodium-sulfur cell under the moving state is adopted, the sodium-sulfur cell can also be used as a power cell to be applied to all industries.

Description

technical field [0001] The invention relates to a sodium-sulfur battery for energy storage and power generation composed of solar light and heat and a sodium-sulfur battery. That is, photoelectric conversion, thermoelectric conversion and sodium, sulfide ion reaction energy storage power generation technology. Background technique [0002] The most commonly used are nickel batteries, lithium batteries, lead-acid batteries and so on. Because their performance lags behind the needs of the times, they are gradually replaced by new batteries. [0003] Now, solar cells are widely used. A total of 1219 Chinese invention patents and utility model patents were retrieved. Most of them are photovoltaic cells, silicon-based thin-film cells, amorphous silicon semiconductor cells, etc. The vigorous development of solar energy utilization Renewable energy is the general direction of global power production in the future. At present, wind power and solar power are the two fastest-grow...

[0009] (3) Electrolyte—calcium (Ca) in conductive ceramics, and micropores are also insulators. When the thermal reaction temperature of the battery rises to a certain value, calcium is released to hinder the ionic radius of the electrolyte, and sodium ions cannot penetrate the ceramic wall. The energy drops rapidly and is scrapped
