DRY ELECTRODE MANUFACTURE FOR SOLID STATE ENERGY STORAGE DEVICES

A method of manufacturing an electrode block for a solid-state battery includes providing an electrode film with a current collector on a first side of the electrode film, coating a layer of dry electrolyte powder on a second side of the electrode film opposite the first side, and pressing the dry electrolyte powder coated on the electrode film to produce a solid electrolyte layer on the electrode film. A method of manufacturing an electrolyte film for a solid-state battery includes preparing a powder mixture including at least one type of fibrillizable binder and at least one type of dry electrolyte powder, the at least one type of dry electrolyte powder being 80-97% of the powder mixture by weight, fibrillizing the at least one type of fibrillizable binder in the powder mixture by subjecting the powder mixture to a shear force, and pressing the powder mixture into a free-standing film.
