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.
Claims7
A battery stack comprising:
- a plurality of cathode leaves connected in series via a plurality of cathode bridges, wherein a cathode slit is disposed between adjacent cathode leaves at each cathode bridge;
- and
- a plurality of anode leaves connected in series via a plurality of anode bridges, wherein an anode slit is disposed between adjacent anode leaves at each anode bridge, and
- wherein the cathode leaves are interleaved with the anode leaves such that each cathode slit receives an anode bridge, and each anode slit receives a cathode bridge, and the anode leaves and cathode leaves are folded together such that the anode leaves and cathode leaves are stacked in an alternating manner to form the battery stack.
The battery stack of 1, wherein each of the cathode slits defines a spacing between adjacent cathode leaves, and
- wherein each of the anode slits defines a spacing between adjacent anode leaves.
