Flexible inorganic fibers and battery electrode containing same
Abstract
Abstract METHOD OF PRODUCING STRONG INORGANIC FIBERS SUCH AS ZINC OXIDE FIBERS, BY FORMING A MIXTURE OF INORGANIC PARTICLES SUCH AS ZINC OXIDE, WITH A PLASTIC BINDER SUCH AS POLYPHENYLENE OXIDE (PPO), IN A FLASH DRYING SOLVENT FOR THE BINDER, SUCH AS CHLOROFORM, FORMING A SLURRY, AND FIBERIZING THE MIXTURE AS BY SPRAYING INTO A CLOSED CHAMBER, TO FLASH THE SOLVENT AND FORM FIBERS OF THE INORGANIC MATERIAL CONTAINING PLASTIC BINDER, SUCH AS ZINC OXIDE FIBERS CONTAINING POLYPHENYLENE OXIDE; SUCH COATED FIBERS CAN BE SINTERED, E.G. AT TEMPERATURE OF THE ORDER OF ABOUT 1000* C., IF DESIRED, TO REMOVE THE ORGANIC BINDER OR RESIDUE, AND FORM STRONG SINTERED FIBERS. THE RESULTING INORGANIC FIBERS, EITHER UNSINTERED OR SINTERED, ARE PARTICULARLY ADAPTED TO BE INCORPORATED INTO BATTERY ELECTRODES, E.G. BY COMPACTING ZINC OXIDE UNSINTERED OR SINTERED FIBERS INTO AN ELECTRODE SHAPE, TO PROVIDE A HIGH STRENGTH POROUS, STABLE ELECTRODE STRUCTURE.
