High-performance rechargeable batteries having a spalled and textured cathode layer
A high-capacity and a high-performance rechargeable battery is provided by forming a rechargeable battery stack that includes a spalled material structure that includes a spalled cathode material layer that has at least one textured surface and a stressor layer that has at least one textured surface. The stressor layer serves as a cathode current collector of the rechargeable battery stack. The at least one textured surface of the spalled cathode material layer forms a large interface area between the cathode and electrolyte which is formed above the spalled cathode material layer. The large interface area between the cathode and the electrolyte reduces interface resistance within the rechargeable battery stack.
