The problem addressed by the present invention is that of specifying a process for the electrochemical production of LiOH from Li+-containing water with the aid of an electrochemical cell with LiSICon membrane that can be operated economically on an industrial scale too. In particular, the process should have good energy efficiency and achieve a high membrane lifetime even when the employed feed contains impurities that are harmful to LiSICon materials. The problem is solved by the flow conditions in the anodic compartment of the electrochemical cell being established such that the anolyte flows along the membrane with a certain minimum crossflow velocity.
