Abstract

A method for manufacturing a solid-state battery device. The method can include providing a substrate within a process region of an apparatus. A cathode source and an anode source can be subjected to one or more energy sources to transfer thermal energy into a portion of the source materials to evaporate into a vapor phase. An ionic species from an ion source can be introduced and a thickness of solid-state battery materials can be formed overlying the surface region by interacting the gaseous species derived from the plurality of electrons and the ionic species. During formation of the thickness of the solid-state battery materials, the surface region can be maintained in a vacuum environment from about 10−6 to 10−4 Torr. Active materials comprising cathode, electrolyte, and anode with non-reactive species can be deposited for the formation of modified modulus layers, such a void or voided porous like materials.
