FIELD: electrical communication engineering.
SUBSTANCE: invention relates to rechargeable electrochemical cells, batteries and supercapacitors. Electrochemical cell for a rechargeable battery includes a solid anode of sodium metal, which is applied to the corresponding current collector during the process of charging the element. Disclosed are several versions of compatible electrolytes, together with new cathode materials for the creation of a complete battery cell with high density energy.
EFFECT: technical result is higher specific energy of element, higher economic efficiency and longer service life.
