Abstract
A method and apparatus for forming lithium-ion batteries and battery cell components, and more specifically, to a system and method for fabricating such batteries and battery cell components using deposition processes that form three-dimensional porous structures are provided. One method comprises texturing a conductive substrate by calendering the conductive substrate between opposing wire mesh structures, forming a first layer of cathodically active material having a first porosity on the surface of the textured conductive substrate, and forming a second layer of cathodically active material having a second porosity on the first layer, wherein the second porosity is greater than the first porosity.
