Abstract
A system for forming a particle layer on a substrate may include at least one sprayer and at least two masks configured to selectively mask a substrate in a first region and second region of the substrate. The at least one sprayer may be configured to spray particles at the substrate, where the at least two masks maintain the first region and second region substantially free of the deposited material. A heater may be employed to heat the substrate as the particles are sprayed by the at least one sprayer onto the substrate.
Claims21
A method for depositing material layers, the method comprising:
- grasping a first region of a substrate with a first clamp to mask the first region of the substrate;
- heating the substrate;
- and
- spraying first particles comprising at least one selected from the group of an electrochemical material, an ionically conductive material, an electrically conductive material, and a separator material towards the heated substrate to form a first layer on the substrate, wherein the substrate is a current collector for an electrochemical cell.
A method of forming an electrode comprising:
- masking a first region of a substrate to inhibit material deposition on the substrate in the first region, wherein masking the first region of the substrate includes grasping the first region of the substrate with a first clamp;
- masking a second region of the substrate to inhibit material deposition in the second region, wherein masking the second region of the substrate includes grasping the second region of the substrate with a second clamp;
- applying first particles comprising at least one selected from the group of an electrochemical material, an ionically conductive material, an electrically conductive material, and a separator material to the substrate to form a first layer;
- and
- applying second particles comprising at least one selected from the group of the electrochemical material, the ionically conductive material, the electrically conductive material, and the separator material to the first layer to form a second layer disposed on the first layer.
