1. A method of assembling a battery cell assembly, comprising:
layering a first electrode with a second electrode in a first direction such that a primary section of the first and second electrodes overlap in the first direction and a first edge section of the first electrode does not overlap with the second electrode in the first direction;
winding the first and second electrodes about an axis perpendicular to the first direction to form a cylindrically-shaped rolled cell with the first edge section disposed on a first end of the rolled cell;
folding a first folded portion of the first edge section to contact an adjacent portion of the first edge section; and
coupling a first end cap to the rolled cell to contact the first folded portion.
