    Abstract: The present invention provides a non-aqueous electrolyte secondary battery that can suppress a drop in a flash point of an electrolyte solution even if the non-aqueous electrolyte secondary battery is used for a long time. The non-aqueous electrolyte secondary battery includes: an electrode body having a structure in which a positive electrode including a positive-electrode active material and a negative electrode including a negative-electrode active material are stacked with a separator interposed therebetween; a non-aqueous electrolyte solution containing a flame retardant; and an outer casing accommodating the electrode body and the non-aqueous electrolyte solution. The non-aqueous electrolyte solution in the electrode body has a flame retardant concentration lower than a flame retardant concentration in the non-aqueous electrolyte solution between the electrode body and the outer casing.

    Abstract: A method for producing a non-aqueous electrolyte secondary battery according to the present invention is characterized in that the method comprises the steps of: placing an electrode body into an outer casing, the electrode body having a folded-separator structure or a wound structure in which a positive electrode including a positive-electrode active material and a negative electrode including a negative-electrode active material are stacked with a separator interposed therebetween; placing a non-aqueous electrolyte free of a flame retardant into the outer casing; charging the electrode body by applying a voltage between the positive electrode and the negative electrode placed in the outer casing; placing a flame retardant into the outer casing; and sealing the outer casing, wherein the step of charging is a step of charging the electrode body with the state in which the surface of the positive-electrode active material and the surface of the negative-electrode active material are in contact with the non-aqueous electrolyte substantially free of the flame retardant.

    Abstract: A method of the present invention for manufacturing a lithium-ion cell comprises the step of impregnating a porous positive-electrode active material layer or a porous negative-electrode active material layer with an ionic liquid electrolyte. The ionic liquid electrolyte includes: an ionic liquid comprising an anion and a cation; and a lithium salt dissolved in the ionic liquid. The anion is bis(fluorosulfonyl)imide ion. The lithium salt is lithium bis(fluorosulfonyl)imide or lithium bis(trifluoromethansulfonyl)imide. The ionic liquid electrolyte contains the lithium salt at a concentration of 1.6 mol/L to 3.2 mol/L inclusive. The step of impregnation with the ionic liquid electrolyte is the step of impregnating the positive-electrode active material layer or the negative-electrode active material layer with the ionic liquid electrolyte at a temperature of 50° C. to 100° C. inclusive.
