ELECTROCHEMICAL PRODUCTION OF HYDROGEN AND LITHIUM HYDROXIDE UNDER DEFINED FLOW CONDITIONS

The invention is based on the object of specifying a method for the electrochemical production of LiOH from Li⁺-containing water with the aid of an electrochemical cell with a LiSICon membrane, which can also be operated economically on an industrial scale. In particular, the method should have high energy efficiency and achieve a long service life of the membrane even when the feed used contains impurities that are harmful to LiSICon materials. The object is solved by adjusting the flow conditions in the anodic compartment of the electrochemical cell such that the anolyte flows along the membrane at a certain minimum overflow velocity.
