Abstract: 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.

Abstract: Rechargeable lithium-ion batteries that have a high-capacity are provided. The lithium-ion batteries contain an anode structure that is of unitary construction and includes a non-porous region and a porous region including a top porous layer (Porous Region 1) having a first thickness and a first porosity, and a bottom porous layer (Porous Region 2) located beneath the top porous layer and forming an interface with the non-porous region. At least an upper portion of the non-porous region and the entirety of the porous region are composed of silicon, and the bottom porous layer has a second thickness that is greater than the first thickness, and a second porosity that is greater than the first porosity.
