The invention relates to the electrochemical production of hydrogen and lithium hydroxide from Li+-containing water with the aid of an LiSICon membrane. It addresses the problem of specifying a process 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. A particular aspect of the process is that the selective separation of lithium by the membrane and an electrolysis of water take place simultaneously in the cell. A key aspect of the process is that the electrochemical process is carried out in basic media, more precisely at pH 9 to 13. The pH is adjusted by adding a basic compound to the feed.
