Abstract: Provided is a method of producing a composite solid electrolyte. The method includes step S10 of producing an oxide-based solid electrolyte membrane by electrospinning a mixture including an oxide-based solid electrolyte precursor and a polymer, step S20 of producing an oxide-based solid electrolyte support by removing the polymer inside the oxide-based solid electrolyte membrane, and step S30 of causing the oxide-based solid electrolyte support to be impregnated with a sulfide-based solid electrolyte using a sulfide-based solid electrolyte precursor solution including a sulfide-based solid electrolyte precursor and a solvent.

Abstract: The present disclosure relates to a delithiation solution and a method for forming an anode active material or an anode using the same. By chemically extracting reactive lithium from a high-capacity anode active material or anode, which has high initial coulombic efficiency due to high lithium content but exhibits decreased stability in dry air or in a solvent for preparation of a slurry, stability can be improve and initial coulombic efficiency can be maintained high. In addition, the method for forming an anode active material or an anode according to the present disclosure can greatly reduce the cost and time required for delivery after production of a lithium-ion battery.

Abstract: Provided are a gel polymer electrolyte and a secondary battery including the same. More particularly, the gel polymer electrolyte includes a sodium cation-containing polymer from which sodium cations can be dissociated, and thus provides improved ion conductivity of sodium cations, thereby improving the electrochemical properties of a secondary battery.
