Method and system for manufacturing battery cell

Abstract

Disclosed is a method of manufacturing a bi-cell of a secondary battery. The bi-cell is configured such that, among electrodes of the bi-cell, a first electrode has a reference surface and is formed to have a designated thickness, a circumference of the reference surface is defined by at least four side parts, and, among the at least four side parts, a first side part and a second side part are symmetrical to each other with respect to a center of the reference surface, and a third side part and a fourth side part are symmetrical to each other with respect to the center of the reference surface, and the method includes adhering first compensation members to the first side part and the second side part simultaneously or at different times, and adhering second compensation members to the third side part and the fourth side part simultaneously or at different times.
