Abstract
A method of forming a solid-state lithium ion rechargeable battery may include depositing a metal layer onto a top surface of a substrate, depositing a handle layer onto a top surface of the metal layer, wherein a portion of the handle layer overlaps the metal layer and the substrate, spalling a portion of the substrate thereby forming a spalled substrate layer, porosifying the spalled substrate layer thereby forming a porous substrate layer, depositing an electrolyte layer onto a top surface of the porous substrate layer, wherein the electrolyte layer is in direct contact with the porous substrate layer, and depositing a cathode onto a top surface of the electrolyte layer. The method may include depositing a cathode contact layer onto a top surface of the cathode, wherein the cathode contact layer is in direct contact with the cathode. The porous substrate layer may be made of silicon.
