Abstract: The present technology relates to a reference point marking apparatus for marking reference points on a pattern electrode in which coated portions and uncoated portions are repeatedly arranged in a longitudinal direction, in which the pattern electrode includes a plurality of reserved electrode lane parts to be slit into a plurality of electrode lanes in the longitudinal direction in a subsequent process, and the reference point marking apparatus includes a moving marking machine configured to mark reference points on uncoated portions of the reserved electrode lane parts arranged in a width direction of the pattern electrode while moving in the width direction, and a controller configured to control an operation of the moving 10 marking machine. The present technology also provides a roll map generation apparatus using the reference point marking apparatus.

Abstract: Systems and methods for manufacturing a battery are disclosed. One system may include: a first cutter configured to cut a first electrode sheet into a first electrode portion; a second cutter configured to cut a second electrode sheet into a second electrode portion having a second length; a winder configured to form an electrode assembly by winding the first electrode portion, the second electrode portion, a separator between the first electrode portion and the second electrode portion; and an identification information assigning device configured to assign identification information to the electrode assembly based on: a cut count value of the first electrode sheet and/or a cut count value of the second electrode sheet; and/or a position coordinate value of the first electrode sheet and/or a position coordinate value of the second electrode sheet.
