METHOD FOR PRODUCING NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY

Document Type and Number:

WIPO Patent Application WO/2014/092121

Kind Code:

A1

Abstract:

This method for producing a non-aqueous electrolyte secondary battery comprises: a step for introducing, into an outer casing, an electrode body that has a folded structure or a wound structure and 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 sandwiched therebetween; a step for introducing, into said outer casing, a non-aqueous electrolyte that does not include a flame retardant; a step for performing charging by applying a voltage between said positive electrode and said negative electrode that have been introduced into said outer casing; a step for introducing a flame retardant into said outer casing; and a step for sealing said outer casing. Said method is characterized in that said charging step is a step for performing charging in a state where the surface of said positive-electrode active material and the surface of said negative-electrode active material are in contact with said non-aqueous electrolyte that substantially does not include a flame retardant.
