  • Publication number: 20180277826
    Abstract: An atmospheric plasma spray device is used to direct a stream of plasma-heated, particulate, lithium battery electrode materials to form a porous layer of the electrode particles on a surface of a compatible current collector metal foil. Subsequently, a non-plasma spray device is used to direct a stream of droplets of an aqueous solution of a polymeric binder material onto and into the porous layer of electrode particles. Water evaporates from the droplets of binder solution as the droplets infiltrate the porous electrode material and coat the electrode particles and current collector surface. When the water (or other solvent) has evaporated from the dispersed droplets of polymer material, the polymer binder bonds the particles to each other and to the current collector surface. The polymer spray may immediately follow the deposition of the electrode particles, or follow later, even at a downstream spray location.

A gaseous mixture is caused to flow through the battery material in the channel. The gaseous mixture includes an organic solvent vapor present in an amount effective to hydrogen bond with at least some water molecules from the battery material. The gaseous mixture is caused to flow through the battery material for a predetermined amount of time, at a predetermined temperature, and at a predetermined pressure. The organic solvent vapor having at least some water molecules bonded thereto is removed from the battery material. The removing takes place for a predetermined amount of time, at a predetermined temperature, and at a predetermined pressure, thereby forming the battery material having reduced residual water content.
