Abstract:
1. A method of creating a battery having a decreased volume interconnection to a terminal comprising: providing at least one electrode stack comprising a plurality of electrodes, said electrode stack having an electrode active area stack comprising a plurality of electrode active areas and an electrode tab stack comprising a plurality of electrode tabs, each electrode having a thickness and each electrode tab having a tip, and the same length between the electrode active area and the tip, wherein all of the tips extend in a common direction; providing a space between adjacent electrodes; folding each said electrode tabs of said plurality of electrode tabs into a compact arrangement such that ends of all of the tips form a plane perpendicular to the common direction; and connecting said electrode tab stack to a connection means, wherein the electrode tabs are folded into the compact arrangement using formulae, wherein N is an outermost folded electrode tab, n is an index number of any specific individual electrode tab numbering 0 for an innermost folded electrode tab to said N, A
