Abstract
A method for manufacturing an electrode assembly is provided. The method includes forming a laminate in which a positive electrode, a separator, and a negative electrode are alternately disposed by alternately arranging positive electrodes and negative electrodes on a separator, which is zigzag folded and forms a bend; fixing positions of the positive electrode and the negative electrode relative to the separator by applying heat and pressure to the laminate; attaching the positive electrode, the separator, and the negative electrode by applying heat and pressure to the laminate; and forming an electrode assembly by cutting a side of the laminate, wherein the side of the laminate includes the bend.
Claims13
A method for manufacturing an electrode assembly, the method comprising:
- (S10) forming a laminate in which a positive electrode, a separator, and a negative electrode are alternately disposed by alternately arranging positive electrodes and negative electrodes on a separator, which is zigzag folded and forms a bend;
- (S20) fixing positions of the positive electrode and the negative electrode relative to the separator by applying heat and pressure to the laminate, wherein the positions of the positive electrode and the negative electrode relative to the separator are fixed by partially attaching the positive electrode and the separator, and the separator and the negative electrode, respectively;
- (S30) attaching the positive electrode, the separator, and the negative electrode by applying heat and pressure to the laminate, wherein the positive electrode and the separator, and the separator and the negative electrode are completely attached, respectively;
- and
- (S40) forming an electrode assembly by cutting a side of the laminate,
- wherein the side of the laminate comprises the bend.
