Flocked plate structure for electric batteries
Abstract
Abstract A CONDUCTIVE METAL STRIP FOR ALKALINE BATTERIES CARRIES AN EFFECTIVELY ORDERED ARRAY OF EXTREMELY THIN, SQUARE NICKEL (OR NICKEL PLATED IRON) FLAKES STACKED APPROXIMATELY NORMAL TO AND TRANSVERSELY OF THE STRIP WITH THEIR EDGES APPROXIMATELY PARALLEL, AND WITH ONE EDGE OF EACH FLAKE CONDUCTIVELY JOINED TO THE STRIP BY A SINTERED NICKEL FILLET. THE FLAKES ARE SLIGHTLY SEPARATED BY THE MODE OF FABRICATION AND BY DEVIATIONS FROM EXACTLY NORMAL AND TRANSVERSE POSITION ON THE STRIP, AND FROM EXACT FLATNESS. THESE DEVIATIONS ARE SO SMALL AS COMPARED TO THE GENERALLY NORMAL AND TRANSVERSE POSITIONS AND THE FLATNESS OF THE FLAKES, THAT THEY PROVIDE ESSENTIALLY REGULAR INTERSTICES WITH OPTIMAL SURFACE AREA OF ACTIVE MATERIAL AND ACCESSIBILITY THEREOF TO ELECTROLYTE, AND MINIMAL VOLUME AND CONDUCTIVE LENGTH OF SUPPORTING MATERIAL. A SUITABLE TECHNIQUE OF FABRICATING A FLOCKED STRIP BY WAY OF MAGNETIC STACKING OF FLAKES ON BELTS AND FINALLY ON THE STRIP, TRAVELING AT DIFFERENT SPEEDS, IS DESCRIBED.
