High-capacity rechargeable battery stacks containing a spalled cathode material
High-capacity (i.e., a capacity of 50 mAh/gm or greater) and high-performance rechargeable batteries are provided that contain a rechargeable battery stack that includes a spalled material structure that includes a cathode material layer that is attached to a stressor material. The cathode material may include a single crystalline that is devoid of polymeric binders. The stressor material serves as a cathode current collector of the rechargeable battery stack.
