Abstract
Techniques disclosed herein include systems and methods that improve the speed of jelly roll assembly for large format and high capacity cells as compared to a stack-folding production method. In one embodiment, a higher speed winding process is achieved, and, in addition, a higher capacity and energy can be achieved by adding at least one (additional) cathode layer between the jelly roll. Such an addition minimizes the loss of use of an anode outer layer.
