Abstract
A battery comprising a plurality of electrode extensions comprising at least one area of at least partial overlap of one extension over another. Typically, said overlaps occur at least near to battery cap contact area for electrode extensions. Said overlaps enable end plate of ‘jelly-roll’ of battery materials to be formed from and maintained by progressive folding down of extensions during battery winding. Such overlaps are suitable for electrical contact to battery cap. Said overlaps enable short average electron path lengths in batteries, and thus mitigate against heat damage to battery during recharge. Said overlaps are supportive of efficient high-speed battery manufacture.
