Abstract

A systems and methods for tracking a position of an electrode. The system may include: a notching controller configured to store pitch information of a unit electrode 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; a roll map generator configured to generate a roll map based on the electrode coordinate information transmitted from the notching controller; 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.

Claims (24)

1 . A system for tracking position of an electrode comprising:

a roll map configured to simulate the electrode;

wherein the roll map comprises electrode coordinates information and a cell identification (ID) of a unit electrode.

2 . The system of claim 1 , wherein the roll map comprises a plurality of roll map bars corresponding to a plurality of detailed processes of electrode manufacturing process; and

wherein the plurality of roll map bars each comprise electrode coordinates based on the removal of the electrode.

3 . The system of claim 1 , wherein the roll map comprises a roll map bar of a notching process; and

wherein the roll map bar of a notching process comprises the cell ID.

4 . The system of claim 1 , wherein the roll map comprises a plurality of roll map bars corresponding to a coating process and a roll press process, respectively; and

wherein the electrode coordinates information comprises relative coordinates of the roll press process, absolute coordinates of the roll press process, relative coordinates of the coating process, and absolute coordinates of the coating process.

5 . A method for tracking position of an electrode comprising:

obtaining a cell identification (ID) of a unit electrode;

calculating coordinates of the cell ID based on the cell ID; and

obtaining location information of the unit electrode based on the coordinates of the cell ID and coordinates of the roll map.

6 . The method of claim 5 , wherein calculating the coordinates of the cell ID based on the cell ID comprises multiplying a sequence number of the cell ID by the width of the unit electrode.

7 . The method of claim 5 , wherein obtaining location information of the unit electrode based on the coordinates of the cell ID and the coordinates of the roll map comprises comparing the coordinates of the cell ID with the coordinates of roll map.

8 . The method of claim 5 , wherein obtaining location information of the unit electrode based on coordinates of the cell ID and the coordinates of the roll map comprises obtaining the coordinates of the roll map corresponding to the cell ID coordinates.

9 . The method of claim 5 , wherein obtaining location information of the unit electrode based on the coordinates of cell ID and the coordinates of the roll map comprises adding length reduction value of the electrode to the coordinates of the cell ID.

10 . The method of claim 5 , wherein the roll map comprises a plurality of roll map bars corresponding to a plurality of detailed processes of electrode manufacturing process; and

wherein obtaining location information of the unit electrode based on the coordinates of cell ID and the coordinates of the roll map comprises adding length reduction value of the electrode based on the coordinates of the cell ID and the roll maps of the plurality of detailed processes.

11 . The method of claim 5 , wherein obtaining location information of the unit electrode based on the coordinates of cell ID and the coordinates of the roll map comprises obtaining relative coordinates of roll press process by adding length reduction value of the electrode removed in the notching process to the coordinates of the cell ID.

12 . The method of claim 11 , wherein obtaining location information of the unit electrode based on the coordinates of cell ID and the coordinates of the roll map further comprises obtaining absolute coordinates of the roll press process by adding length reduction value of the electrode removed after the roll press process to the relative coordinates of the roll press process.

13 . The method of claim 12 , wherein obtaining location information of the unit electrode based on the coordinates of cell ID and the coordinates of the roll map further comprises obtaining a first relative coordinates of coating process by adding length reduction value of the electrode removed during the roll press process to the absolute coordinates of the roll press process.

14 . The method of claim 13 , wherein obtaining location information of the unit electrode based on the coordinates of cell ID and the coordinates of the roll map further comprises obtaining a second relative coordinate of the coating process by dividing the first relative coordinates by elongation ratio in the roll press process.

15 . The method of claim 14 , wherein obtaining location information of the unit electrode based on the coordinates of cell ID and the coordinates of the roll map further comprises obtaining absolute coordinates of the coating process by adding length reduction value of the electrode removed after the coating process to the first relative coordinates or the second relative coordinates.
