Abstract
There are provided a method of manufacturing a jelly roll-type electrode assembly and a method of manufacturing a secondary battery using the electrode assembly. The method of manufacturing the electrode assembly includes notching a cathode and an anode, elongated in one direction, in a constant size and shape to form a plurality of electrode units, laminating the cathode and the anode with a separator disposed therebetween to form a unit cell, and winding the unit cell by bending the connection units so that the electrode units of the cathode and the anode overlap each other. In the manufacturing of the jelly roll-type electrode assembly and the polymer secondary battery, whose production process can be easily simplified, a jelly roll-type electrode assembly and a polymer secondary battery, both of which exhibit excellent design flexibility, can be manufactured.
