1. A method for manufacturing a solid-state battery, the method comprising:
forming an anode layer;
forming a solid-state ionic conductive membrane layer; and
forming a composite cathode layer formed onto a positive current collector using an energy-assisted solvent-free spray process, the composite cathode comprising:
core-shell structures, wherein the core is the active cathode material, and the shell is a mixture of ionically conductive catholyte and an electronically conductive additive.
