PURIFICATION OF IMPURE ALKALI METAL SALTS BY CALCIUM CARBIDE

摘要

Process for purifying an ionic electrolyte containing at least one salt alkaline earth, the process comprising at least one step of contacting particles of at least one calcium salt, especially calcium carbide. The method makes it possible to obtain new electrolytes characterized in particular by a particularly low water content. The generators electrochemical corresponding which integrate the electrolyte as a constituent element characterized by remarkable stability and are particularly safe.
