A system for the automated coiling of a jelly roll electrode assembly for controlled assembly and tensioning of jelly roll assembly is provided. The system includes: a shuttle, and a mandrel to which electrodes are welded; a base, mateable with the shuttle and on which the battery head assembly is mounted for welding to the mandrel; and a coiling device. The coiling device has an upper spool, a lower spool, holding a separator strip and a platform between the two holding the base. The separator strip is threaded through a passage in the mandrel separating positive and negative portions. Rotating the mandrel coils the positive electrode, the separator strip and the negative electrode to coil around the mandrel. The coiling device may include a feedback loop braking one or both spools and allowing the coiling tension to be programmed to a desired level.

1. A system for preparing an electrode assembly comprising separately: a base comprising a right member and a left member connected by a central member wherein the central member accepts an electrode assembly header; anda shuttle, comprising a right portion and a left portion connected by a center portion, wherein the left portion comprises a left main cover and a left secondary cover closeable over the left portion of the shuttle, the right portion comprises a main right cover and a right secondary cover closeable over the right portion of the shuttle, and the center portion holds a mandrel, wherein the left and right main and secondary covers are positioned on opposite sides of the shuttle and are discontinuous with each other,wherein the base mates with the shuttle, such that the mandrel mates with the electrode assembly header between the center portion of the shuttle and central member of the base. 2. The system of claim 1, wherein the center portion of the shuttle further comprises a ligature to support the mandrel. 3. The system of claim 1, wherein the central member further includes a rotatable portion, wherein the rotatable portion is configured to accept a portion of the electrode assembly header. 4. The system of claim 3, wherein the central member is configured to accept a drive barrel, wherein the drive barrel includes the electrode assembly header. 5. The system of claim 4, wherein the drive barrel further includes a barrel shaft that rotatably engages with the central member. 6. The system of claim 1, wherein one of the left member or right member includes a drive shaft, the drive shaft having a first end and a second end, the second end including a drive belt wherein the drive belt engages a barrel shaft, and the first end is configured to engage with a second drive shaft. 7. The system of claim 1, wherein the mandrel comprises a positive portion, a negative portion, a removable portion connecting the positive portion and the negative portion and a passage between the positive portion and the negative portion. 8. The system of claim 7, wherein a ligature engages the removable portion. 9. The system of claim 8, wherein a body portion of the ligature is configured to hold the removable portion of the mandrel. 10. The system of claim 1, wherein one or more of the left and right main and secondary covers are magnetically closable over the corresponding left and right portions of the shuttle. 11. A method to prepare an electrode assembly using the system of claim 1 comprising the steps: placing the mandrel into the central portion of the shuttle; andmating the shuttle with the base. 12. The method of claim 11, wherein the center portion of the shuttle further comprises a ligature to support the mandrel. 13. The method of claim 11, wherein the central member further includes a rotatable portion, wherein the rotatable portion accepts a portion of the electrode assembly header. 14. The method of claim 13, wherein the central member accepts a drive barrel, wherein the drive barrel includes the electrode assembly header. 15. The method of claim 14, wherein the drive barrel further includes a barrel shaft that rotatably engages with the central member. 16. The method of claim 11, wherein one of the left member or right member includes a drive shaft, the drive shaft having a first end and a second end, the second end including a drive belt wherein the drive belt engages the barrel shaft, and the first end is configured to engage with a second drive shaft. 17. The method of claim 11, wherein the mandrel comprises a positive portion, a negative portion, a removable portion connecting the positive portion and the negative portion and a passage between the positive portion and the negative portion. 18. The method of claim 17, wherein a ligature engages the removable portion. 19. The method of claim 18, wherein a body portion of the ligature holds the removable portion of the mandrel. 20. The method of claim 19, wherein a stem of the ligature passes through a drive hole in the center portion of the shuttle. 21. A system for preparing an electrode assembly comprising separately: a base comprising a right member and a left member connected by a central member wherein the central member is configured to accept an electrode assembly header; anda shuttle, comprising a right portion and a left portion connected by a center portion, wherein the left portion comprises a left cover, the right portion comprises a right cover, and the center portion is configured to hold a mandrel, wherein the left and right covers are positioned on opposite sides of the shuttle,wherein the base is configured to mate with the shuttle, such that the mandrel mates with the electrode assembly header between the center portion of the shuttle and central member of the base,wherein the mandrel comprises a positive portion, a negative portion, a removable portion connecting the positive portion and the negative portion and a passage between the positive portion and the negative portion,wherein a ligature engages the removable portion,wherein a body portion of the ligature is configured to hold the removable portion of the mandrel, andwherein a stem of the ligature is configured to pass through a drive hole in the center portion of the shuttle.
