Abstract: A gradient multilayer structure for lithium batteries, a method for manufacturing thereof, and a lithium batteries comprise gradient multilayer structures. The multilayer structure has a porosity gradient with respect to adjacent layers of the multilayer structure or a solid-state ionic conductive material gradient with respect to adjacent layers of the multilayer structure.
