Abstract
Abstract Lithium metal is environmentally sensitive and highly reactive, especially when coupled with flammable organic electrolytes, which pose critical safety challenges for lithium metal batteries under harsh operational conditions. This study tackles this challenge by constructing an integrated strategy for encapsulating lithium metal with a multifunctional polyfluoride ionogel (PFIGE) through in situ thermal polymerization. Based on the cross‐linking network design of hexafluorobutyl methacrylate monomer and 1‐butyl‐3‐lithium bis(trifluoromethylsulfonyl)imide ionic liquid plasticizer, C−F group and TFSI − anion cooperate to confer excellent water/oxygen barrier properties of the PFIGE. Meanwhile, the…
