A Novel Cellulose-Supported Polymer Electrolyte with High Ionic Conductivity for Lithium Metal Batteries.

ABSTRACT: The traditional liquid electrolytes pose safety hazards primarily attributed to the flammability of organic solvent, whereas solid-state electrolytes can significantly enhance the safety of lithium-ion batteries. Polymer solid electrolytes are being considered as an effective solution due to their excellent flexibility and low cost, but they suffer low ionic conductivity or high interface impedance. Here, the ketone-containing allyl acetoacetate monomers were polymerized within the cellulose membrane via UV photopolymerization to prepare a cellulose-supported poly-allyl acetoacetate polymer electrolyte. The PAAA electrolyte shows the ion conductivity of 1.14 × 10^-4 S cm^-1 and the electrochemical stability window of 4.5 V. The Li symmetric battery can stably cycle for
