Abstract
Disclosed herein is a method of manufacturing a battery cell having a structure in which an electrode assembly including a positive electrode, a separator, and a negative electrode is mounted in a battery case, and the battery case is sealed by thermal welding, the method including (a) mounting the electrode assembly in a receiving part of the battery case and forming sealed portions at an outer edge of the receiving part by thermal welding, (b) perpendicularly bending the sealed portions and bringing the bent sealed portions into contact with an outer side wall of the receiving part, (c) mounting and fixing the battery case processed at step (b) in a jig provided with a depressed part having a size corresponding to that of the battery case, and (d) injecting a curable material into a space defined between the outer side wall of the receiving part of the battery case and an inner side wall of the depressed part of the jig and curing the injected curable material.
