Abstract
A method and apparatus for forming an electrochemical layer of a lithium ion battery is provided. A precursor mixture in a carrying medium is activated in a reactor chamber by application of energy to synthesize active materials. The activated precursor mixture is then spray deposited on a substrate. A binder and conductive materials may be blended, or sprayed separately, with the nano- or micro-crystals as they deposit on the surface to enhance adhesion and conductivity.
