Abstract:
The present invention is directed to the realization that the dimensions and basis weight of an electrode active admixture such as a transition metal oxide, and particularly silver vanadium oxide, formed into an electrode structure from an admixture paste subjected to a calendering process are influenced by the calender direction. To obtain electrode structures of a desired low basis weight requires a secondary calendering step performed in a direction reverse or orthogonal to that used to form the initial sheet tape. Orthogonal or reverse feed of the electrode active admixture provides for fibrillation of the fluoro-polymeric binder in other than the initial direction. This lets the binder spread in directions transverse to the initial direction to form the low basis weight electrode active structure.
