  • Patent number: 11078565
    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.

  • Patent number: 10593985
    Abstract: A method of fabricating a multilayered thin film solid state battery device. The method steps include, but are not limited to, the forming of the following layers: substrate member, a barrier material, a first electrode material, a thickness of cathode material, an electrolyte, an anode material, and a second electrode material. The formation of the barrier material can include forming a polymer material being configured to substantially block a migration of an active metal species to the substrate member, and being characterized by a barrier degrading temperature. The formation of cathode material can include forming a cathode material having an amorphous characteristic, while maintaining a temperature of about ?40 Degrees Celsius to no greater than 500 Degrees Celsius such that a spatial volume is characterized by an external border region of the cathode material. The method can then involve transferring the resulting thin film solid state battery device.
