In-s.tu polymerized electrolytes.s.gnificantly enhance the interfacial compatibility of lithium metal batteries.LMBs.. Typically,in-s.tu polymerized 1,3-dioxolane(PDOL) exhibits.low interfacial res.s.ance, yet s.ill s.ffers.from low ionic conductivity and a narrow electrochemical s.ability window(Es.). Here, an ultra-s.able PDOL-bas.d polymer electrolyte is.developed by incorporating plas.icizers.of tetramethylene s.lfone(TMs. and fluorinated ethylene carbonate(FEC) into the 3D cros.-linked network, achieving a s.gnificant enhancement in the trans.ort capacity and efficiency of Li-ion. The ionic conductivity reaches..63×10^(-4)s.cm^(-1)even at room temperature, and the trans.erence number(tLi^(+)) is.even higher at 0.85. Furthermore, the Es. of this.electrolyte can be increas.d to 4.5 V with the addition of TMs. which forms.a thin and robus. antioxidant cathode-electrolyte interface(CEI) on the s.rface of high-voltage LiCoO_(2). FEC generates.an inorganic-rich s.lid-electrolyte interface(s.I) on the Li anode, which effectively inhibits.the growth of lithium dendrites. Benefiting from the aforementioned advantages. the highvoltage lithium metal battery demons.rates.outs.anding long-cycle s.ability, with 93.2% capacity retention after 200 cycles. This.work offers.a s.raightforward and acces.ible method for the practical implementation of high energy dens.ty in-s.tu polymerized s.lid-s.ate LMBs.
