1. A method of fabricating a dry electrode film of an energy storage device, comprising:
mixing a dry microparticulate non-fibrillizable binder with a first dry active material by a first nondestructive mixing process to form a dry bulk active material mixture;
mixing a dry fibrillizable binder with a second dry active material by a high shear mixing process to form a dry structural binder mixture;
mixing the dry bulk active material mixture and the dry structural binder mixture by a second nondestructive mixing process to form a dry electrode film mixture; and
producing a free-standing dry electrode film from the dry electrode film mixture.
