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 having a first length, the first electrode sheet comprising a first coated portion; a second cutter configured to cut a second electrode sheet into a second electrode portion having a second length, the second electrode sheet comprising a second coated portion; a winder configured to wind the first electrode portion, the second electrode portion, and a separator to form an electrode assembly; 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 first pattern indication of the first electrode sheet and/or a second pattern indication of the second electrode sheet.

Abstract: A battery manufacturing method according to an embodiment includes a first operation of acquiring pattern indicator data and measurement data and/or inspection data for an electrode sheet having patterns in which coated portions and uncoated portion are repeatedly arranged, and the pattern indicator data includes representing positions of the patterns at the electrode sheet; a second operation of associating the measurement data and/or inspection data with the pattern indicator data; and a third operation of generating inter-process monitoring data by matching the pattern indicator data for each process of a plurality of processes so as to correspond to a same physical position of the electrode sheet.

Abstract: A method of manufacturing a battery includes generating pattern indicator data that includes representing a plurality of positions at a patterned electrode sheet in which coated portions and uncoated portions are repeatedly arranged, and a coated portion and an uncoated portion adjacent to the coated portion constituting a pattern, where a position of the plurality of positions being a position of at least one coated portion and an adjacent uncoated portion at the patterned electrode sheet. The method includes generating measurement data and/or inspection data for the patterned electrode sheet; associating the generated measurement data and/or inspection data with the pattern indicator data; and generating monitoring data for manufacturing the battery based on the associated measurement data and/or inspection data and the pattern indicator data.

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.
