Embodiment approach
[0028] Figure 2a is a perspective view of an electrode assembly with a divided support band according to an exemplary embodiment of the present invention.
[0029] Such as Figure 2a As shown, the present invention comprises an electrode assembly 11 , a cathode tab 12 , an anode tab 13 and a separate support strip 24 .
[0030] To manufacture the electrode assembly 11, an active material is applied to both surfaces of the collector. Then, the collector electrode is dried and subjected to roll processing so that the collector electrode is cut into anode plates and cathode plates. In this state, the anode plate and the cathode plate are wound with a separator interposed between the anode plate and the cathode plate to form the electrode assembly 11 . That is, after anode plates and cathode plates are alternately arranged around the separator, an electrode assembly is formed by winding the anode plates and cathode plates in a spiral pattern using an elliptical winding mandrel...
