Self-degrading functional unit introduction for anti-oxidation ability enhancement of a poly(vinyl ethylene carbonate) electrolyte

A novel poly(vinyl ethylene carbonate-3-sulfolene) electrolyte has been developed by copolymerizing monomer precursors, which has a wide electrochemical stability window of 5 V ( vs. Li + /Li) attributed to the pre-degradation of sulfolene-based functional units.
