Abstract
A process for fabricating an electrode for use in an electrochemical cell comprising the steps of: a) associating a current collector with an active material having a surface; b) applying an overlayment material to a substrate; c) associating the overlayment material with at least a portion of the surface of the active material; d) at least alternatively partially curing the active material; and e) removing the substrate and, in turn transferring at least a portion of the overlayment material to at least a portion of the active material. The electrode produced is used in an electrochemical cell comprising a current collector, an electrode active material having a surface, and an overlayment material associated with at least a portion of the active material. The electrode further includes means for increasing compatability of the electrode with an associated electrolyte.
