摘要： A battery cell and a method of manufacturing the battery cell are provided, in which a swelling degree of the battery cell may be precisely measured. A battery cell includes a grid on a surface portion of the battery cell. A method of manufacturing a battery cell includes printing a grid on a surface portion of a battery cell, tubing the surface portion on which the grid is printed to mount the surface portion on an outer surface of the battery cell, and measuring a swelling degree of the battery cell with respect to a grid lattice shape of the surface portion after tubing, as a reference shape.
