摘要： A system for tracking a position of an electrode, which includes a notching controller configured to store pitch information representing a width of a unit electrode subjected to notching and to acquire electrode coordinate information of the electrode in a roll-to-roll state during a notching process and a cell identification (ID) of the unit electrode; a calculator configured to calculate coordinates of the cell ID from the pitch information and the cell ID acquired by the notching controller, wherein the coordinates of the cell ID represent a position of the unit electrode during the notching process; a roll map generator configured to generate a roll map based on the electrode coordinate information transmitted from the notching controller, wherein the roll map includes coordinates of the roll map based on a dimension in a length direction of the electrode to determine a change in an electrode length during an electrode manufacturing process prior to the notching process; and a mapping part configured to compare the coordinates of the roll map with the coordinates of the cell ID to derive an electrode position of the electrode during the electrode manufacturing process from which the unit electrode originates.
