Abstract:
A method and apparatus for forming battery active material on a substrate are disclosed. In one embodiment, an apparatus for depositing a battery active material on a surface of a substrate includes a substrate conveyor system for transporting the substrate within the apparatus, a material spray assembly disposed above the substrate conveyor system, and a first heating element disposed adjacent to the material spray assembly above the substrate conveyor system configured to heat the substrate. The material spray assembly has a 2-D array of nozzles configured to electrospray an electrode forming solution on the surface of the substrate.
