Abstract
A method for forming one or more layers of a lithium-ion battery includes a step of sequentially depositing a wet coating and a free-standing material layer onto a moving substrate to form a first bilayer on the substrate. The first bilayer including a wet coating-derived layer and the free-standing material layer. The first bilayer is heat roll pressed to form a second bilayer in which the wet coating-derived layer is at least partially dried and adhered to the free-standing material layer.
