Abstract
A cathode element is formed as a continuous single element with a plurality of cathode leaves connected by cathode bridges. An anode element is similarly formed as a continuous single element with a plurality of anode leaves connected by anode bridges. The cathode element and anode element can be aligned and interleaved at spaces between adjacent leaves. The resulting battery pre-stack can then be folded along its bridges in alternating directions to form a battery stack whose layers alternate between an anode and cathode, and which requires minimal components and minimal or no welds.
