Abstract
The invention relates to a rechargeable battery based on lithium metal as anode. The rechargeable lithium metal battery according to the invention comprises an electrolyte and also chlorine and fluorine containing compounds: The battery according to the invention has, in particular, a strongly improved Coulomb efficiency of the metallic lithium. In addition, due to gel formation, a much safer system is formed than with liquid electrolyte.
