Abrégé

An multi-stage electrolyzer cell is disclosed. The multi-stage electrolyzer cell comprises an anode, a cathode and at least one ion exchange membrane separating the anode and the cathode. The anode and cathode are exposed in the respective anode chamber and cathode chamber. At least one partition is arranged within at least one of the anode and cathode chambers, dividing the at least one chamber into a plurality of process stages. Each of the partitions comprises a feed port, allowing an electrolyte solution to transport sequentially through each of the plurality of process stages. Means are arranged to transport the electrolyte solution through each one of the plurality of process stages. A multi-stage electrolytic method is also disclosed.

Abrégé

An apparatus and method for converting lithium chloride into lithium hydroxide by electrolysis in an energy efficient manner. A dilute lithium chloride solution produced in the anolyte compartment of the electrolyzer cell is concentrated by means of flash evaporation using heat generated by the operation of the electrolyzer cell. The concentrated lithium chloride solution is recycled to the electrolyzer cell. The use in the flash evaporation of heat energy that would otherwise be released to the environment and wasted results in reduced energy consumption for the conversion process.
