Abstract
Provided are a method of preparing an electrode assembly, in which both sides of a single current collector are coated to form an anode and a cathode, and the current collector is then bent into a vertical sectional zigzag shape and integrated in a state of disposing a separator at interfaces between facing electrode patterns, an electrode assembly prepared by the above method, and a secondary battery comprising the electrode assembly.
Claims16
A method of preparing an electrode assembly, the method comprising:
- preparing a single current collector;
- respectively and repeatedly coating both sides of the single current collector with a cathode active material and an anode active material to form one or more anode patterns and cathode patterns and one or more non-coating portions on which the active materials are not coated;
- bending the one or more non-coating portions, on which the active materials are not coated, into a vertical sectional zigzag shape;
- disposing a separator at respective interfaces between the cathode patterns and the anode patterns that face each other by the bending, and folding the single current collector;
- and
- cutting the bent non-coating portions.
