Abstract: The invention relates to an electrode formed by the blending of dry active powdery electrode forming materials with an aqueous binder dispersion, and the subsequent adhering of the wet binder/dry active powdery electrode-forming materials blend to an electroconductive substrate, resulting in an electrode. The aqueous binder is preferably a fluoropolymer, and more preferably polyvinylidene fluoride (PVDF). The hybrid process provides the good dispersion and small particle size of a wet process, with the energy savings and reduced environmental impact of a dry process. The resulting electrode is useful in energy-storage devices.
