ACCUMULATOR WITH SODIUM ANODE AND CERAMIC ELECTROLYTE

FIELD: electricity. ^ SUBSTANCE: invention is related to the field of power accumulation. According to invention accumulator contains sodium anode, complex chlorine-metal cathode, which includes metal chlorides (nickel and (or) iron chlorides) and liquid electrolyte on the basis sodium chloroaluminate, and ceramic hard electrolyte on the basis of sodium beta-alumina, which separates cathode reagents from sodium anode, which is installed between accumulator casing and ceramic electrolyte. The latter is arranged in the form of thin-walled test tube, which is connected from the side of open end with bottom end of external coaxially installed thin-walled tube of the same material of larger diameter, creating cavity between them, into which cathode reagents are installed as well as thin-walled current collector, which is equidistant from external surface of ceramic test tube and internal surface of ceramic tube, which is fixed with its other end to ceramic insulating ring. ^ EFFECT: increase of accumulator specific capacity. ^ 4 dwg
