1. A method of manufacturing an electrode, comprising the steps of:
- milling dry carbon and dry binder particles, wherein the dry binder particles consist essentially of fibrillizable binder particles and wherein the milling takes place in the absence of solvent and other binders to fibrillize said fibrillizable binder particles and to create a milled dry mixture;
compressing the milled dry mixture into a dry film; and
applying the dry film to a substrate to form an electrode.
