Hybrid electrolyte of ionic liquid and ethers is used to passivate the surface of Li metal surface via modification of the as‐formed solid electrolyte interphase with N‐propyl‐N‐methylpyrrolidinium bis(trifluoromethanesulfonyl)amide (Py13TFSI), thereby reducing the side reactions between the Li metal and electrolyte, leading to remarkably suppressed Li dendrite growth and mitigating Li metal corrosion.
