Battery manufacturing apparatus

A battery manufacturing apparatus, comprising:

• a negative electrode notching device configured to assign a first electrode ID to a first notched electrode for a plurality of first notched electrodes;
• a first cutting device for separating the plurality of first notched electrodes to which the first electrode IDs are assigned into individual negative electrodes;
• a positive electrode notching device configured to assign a second electrode ID to a second notched electrode for a plurality of second notched electrodes;
• a second cutting device for separating the plurality of second notched electrodes to which the second IDs are assigned into individual positive electrodes;
• a stacking device configured to stack the individual positive electrodes and the individual negative electrodes with a separator therebetween;
• and
• a roll map creating device,
• wherein the roll map creating device is configured to create a first roll map indicating process data of a negative electrode on a plane simulating the negative electrode moving between an unwinder and a rewinder of the negative electrode notching device, and
• create a second roll map indicating process data of a positive electrode on a plane simulating the positive electrode moving between an unwinder and a rewinder of the positive electrode notching device,
• wherein the negative electrode notching device comprises a first marking device which is capable of marking a mark corresponding to a first electrode ID on an uncoated portion of the negative electrode, and
• the positive electrode notching device comprises a second marking device which is capable of marking a mark corresponding to a second electrode ID on an uncoated portion of the positive electrode.
