FIELD: electrolyzers for production of alkali metals, such as lithium, sodium and potassium from aqueous solution of alkali metal salt.
SUBSTANCE: proposed electrolyzer includes anode kettle with aqueous solution of at least one salt of alkali metal, cathode kettle and solid electrolyte separating the anode kettle from cathode kettle. Part of surface of solid electrolyte which is in contact with cathode kettle has at least one ion-conducting protective layer.
EFFECT: possibility of working in continuous mode; reduced power requirements.
