A well-orchestrated ether-dominated electrolyte was formulated to stabilize Li surface with the mixture of lithium fluoride and nitride from fluorine-rich carbonate and cyclophosphonitrile. The mixed ionic conducting interphase enables the ether electrolyte to break through the 4-Volt voltage limit at a conventional Li salt concentration and work with high efficiency. The joint effect of formed surface protection layer and elaborated solvent formulation is crucial to extend the electrochemical

摘要：
The lithium (Li) metal battery reveals appealing merits in energy density but suffers from problems of dendrite growth and low coulombic efficiency before its applications. The ether electrolytes entitle Li metal batteries with more smooth Li stripping/deposition but narrow electrochemical stability in contrast to carbonate electrolyte. circumventing this contradictory, a lithium fluoride-nitride mixed ionic conducting interphase was embedded on lithium surface via formulated fluorine-rich carbonate and cyclophosphonitrile, which renders a dend...
