Solid-state electrolytes have been developed for the replacement of aqueous electrolytes for safer lithium batteries. Solid polymer electrolyte system Polyethylene Oxide with Lithium Bis(trifluoromethanesulfonyl)amide in lithium metal battery has been extensively studied without notable breakthroughs due to poor cycling performance. In this study, a novel type of solid polymer electrolyte (Polyethylene Oxide - Lithium Bis(trifluoromethanesulfonyl)amide - Ultra-High Molecular Weight Polyethylene) is synthesized via the solution casting method to impregnate (Polyethylene Oxide-Lithium Bis(trifluoromethanesulfonyl)amide) electrolyte into Ultra-High Molecular Weight Polyethylene membrane pores.

Solid-state electrolytes have been developed for the replacement of aqueous electrolytes for safer lithium batteries. Solid polymer electrolyte system Polyethylene Oxide with Lithium Bis(trifluoromethanesulfonyl)amide in lithium metal battery has been extensively studied without notable breakthroughs due to poor cycling performance. In this study, a novel type of solid polymer electrolyte (Polyethylene Oxide - Lithium Bis(trifluoromethanesulfonyl)amide - Ultra-High Molecular Weight Polyethylene) is synthesized via the solution casting method to impregnate (Polyethylene Oxide-Lithium Bis(trifluoromethanesulfonyl)amide) electrolyte into Ultra-High Molecular Weight Polyethylene membrane pores. The synthesized electrolyte shows excellent electrochemical performance in an all solid-state lithium metal battery. It shows a stable cycling profile in an average 135 mAh g^-1 specific capacity for more than 745 cycles at 1C charge rate. In addition, (Polyethylene Oxide - Lithium Bis(trifluoromethanesulfonyl)amide - Ultra-High Molecular Weight Polyethylene) electrolyte also shows excellent cyclicability. It can withstand more than 1000 cycles at 2.5 mA cm^-2 and clearly demonstrate the lithium dendrite suppression as a self-healing effect.
