METHOD OF MANUFACTURING CURVED SECONDARY BATTERY

摘要

A method of manufacturing a curved secondary battery, the method including preparing a flat secondary battery such that the flat secondary battery includes an electrode assembly and a pouch accommodating the electrode assembly; primary shaping the secondary battery such that the primary shaping includes disposing the flat secondary battery in a first jig, and pressing the flat secondary battery to form a primarily-shaped secondary battery such that the primarily-shaped secondary battery has a first curvature radius; secondary shaping the secondary battery such that the secondary shaping includes disposing the primarily-shaped secondary battery in a second jig, and pressing the primarily-shaped secondary battery to form a secondarily-shaped secondary battery having a second curvature radius; and maintaining the secondarily-shaped secondary battery after forming thereof in the second jig for a predetermined time period.

1. A method of manufacturing a curved secondary battery, the method comprising:
preparing a flat secondary battery such that the flat secondary battery includes an electrode assembly and a pouch accommodating the electrode assembly; primary shaping the secondary battery such that the primary shaping includes:
disposing the flat secondary battery in a first jig, andpressing the flat secondary battery to form a primarily-shaped secondary battery such that the primarily-shaped secondary battery has a first curvature radius; secondary shaping the secondary battery such that the secondary shaping includes:
disposing the primarily-shaped secondary battery in a second jig, andpressing the primarily-shaped secondary battery to form a secondarily-shaped secondary battery having a second curvature radius; and maintaining the secondarily-shaped secondary battery after forming thereof in the second jig for a predetermined time period.
