The process shall especially exhibit a high energy efficiency and achieve a long service life of the membrane even when the employed feed contains impurities harmful to LiSICon materials. A particular aspect of the process is that the cell simultaneously separates off the lithium via the membrane and effects electrolysis of water. An essential aspect of the process is that the electrochemical process is performed in a basic environment, more precisely at pH 9 to 13. The pH is adjusted by addition of a basic compound to the feed.
