and u215eth of the electrode length as possible to thereby minimize the distance that current must travel through the electrode in order to get out and into the battery terminals other arrangements using more or less than 4 tabs are also contemplated once wound together the jellyroll has the respective four tabs sticking out of either end as is illustrated in fig1 these tabs are gathered together and connected to an external terminal as illustrated in fig7 a and 7b according to one or more embodiments of the present invention a cell tabbing design is provided to control and capture all of the tabs in a volumetrically efficient manufacturable and mechanically robust manner in one aspect of the tab design the thickness of the materials that make up the jellyroll is controlled each of the materials anode electrode cathode electrode and separator have thickness controlled to a very tight tolerance approximately u2212 2 um each this allows one to model and reliably predict exactly how these materials will spiral up into a jellyroll including the number of turns and the finished diameter this permits the accurate location of the tabs within the jellyroll in another aspect of tab design the tab positions on the electrodes are selected before they are wound into the jellyroll the tabs are placed along the length of each of the electrodes in positions that are both close to the u215b th.
