Abstract
The subject invention provides a three-step process for electrolyte deposition. A surplus of electrolyte pre-wet material, having a relatively low viscosity, is layered onto a dry, porous electrode. Surplus pre-wet material is mechanically removed from the surface of the electrode. This also removes bubbles or foaminess which has developed in the pre-wet material. The pre-wet solution is allowed to absorb into the porous electrode, and the surface is then coated with the high-viscosity electrolyte precursor. Curing or further processing of the electrode/electrolyte then continues with standard processes.
