Claim:
1. A method of fabricating a multilayered thin film solid state battery device, the method comprising: providing a substrate member, the substrate member comprising a surface region, the substrate member having a melting point temperature; forming a barrier material comprising a polymer material overlying the surface region, the barrier 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; forming a first electrode material overlying the surface region; forming a thickness of 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, an effective diffusivity is characterizing the thickness of the cathode material and having a value ranging from 0.005 μm to 1000 μm, and a void region characterizing the thickness of cathode material, the void region being 0.001% to 20% of the spatial volume; forming an electrolyte configured overlying the thickness of cathode material; forming an anode material overlying the electrolyte; forming a second electrode material overlying the anode material; and transferring a thin film solid state battery device characterized by an energy density ranging from 50 Watt-hour/liter to 3000 Watt-hour/liter.
