摘要：
Process for the purification of an ionic electrolyte comprising at least one alkali metal salt, the process having at least one stage in which particles of at least one calcium salt are brought into contact. The process makes it possible to obtain electrolytes characterized in particular by a particularly low water content. The corresponding electrochemical generators which incorporate the electrolyte as constituent component are characterized by a noteworthy stability and are particularly safe.
