A rare-earth triflate catalyst, Sc(OTf)(3), was used for ring-opening polymerization of 1,3-dioxolane and in-situ production of a quasi-solid-state poly(1,3-dioxolane) electrolyte. It exhibited superior ionic conductivity and achieved dendrite-free lithium deposition and high Coulombic efficiency over 200 cycles.
We report a rare-earth triflate catalyst Sc(OTf)(3) for the ring-opening polymerization of 1,3-dioxolane and the in situ production of a quasi-solid-state poly(1,3-dioxolane) electrolyte, which not only demonstrates a superior ionic conductivity of 1.07 mS cm(-1) at room temperature, but achieves dendrite-free lithium deposition and a high Coulombic efficiency of 92.3% over 200 Li plating/striping cycles.
