ABSTRACT:
Improved adhesion of an electrode layer with an electrolyte or separator layer can be achieved by substantially preventing polymer binder and plasticizer from absorbing into the substrate. This is achieved by impregnating the substrate with polymer and plasticizer prior to applying the electrode mixture which contains an electrode active material, polymer binder, plasticizer, and solvent onto the substrate. Alternatively, prior to applying the electrode mixture, a coating containing a mixture of polymer and plasticizer is applied unto the substrate to form a coated substrate wherein the coating is substantially pervious to solvent and is substantially impervious to said polymer and plasticizer.
