ABSTRACT:
In a new process for making an electrode current collector assembly, an electrode composition is mixed with a volatile casting solvent and is coated onto a substrate. Then, the coated substrate is heated to drive off a major portion of the volatile casting solvent. Next, force is applied on an external surface of the coating and directed toward the substrate so as to compact the coating and reduce the volume of pore spaces in the coating. An electrolyte composition may be applied to the compacted electrode composition either before or after curing. The electrode and electrolyte compositions are each cured. In a final step, a counter-electrode layer is applied onto the electrolyte composition to form a cell assembly.
