Claim 1
Independent Claim
120 words
THE METHOD OF MANUFACTURING A STORAGE ELECTRODE COMPRISING THE STEPS OF FORMING A VAPORIZABLE SUPPORT FILM ACROSS A SUPPORT MEMBER, DEPOSITING ON SAID FILM A FIRST LAYER OF A NOBLE METAL WHICH DOES NOT READILY REACT WITH THE INGREDIENTS OF SAID SUPPORT FILM, DEPOSITING A LAYER OF METALLIC MAGNESIUM ON SAID FIRST LAYER OF METAL, AND HEATING THE ASSEMBLY IN AN OXIDIZING ATMOSPHERE TO DECOMPOSE AND VAPORIZE SAID VAPORIZABLE FILM AND TO CONVERT SAID MANNESIUM TO A TAUT HOMOGENEOUS POLYCRYSTALLINE MAGNESIUM OXIDE MEMBER SUPPORTED BY SAID SUPPORT MEMBER, SAID HEATING STEP FURTHER RESULTS IN COAGULATING SAID NOBLE METAL TO PROVIDE A DISCONTINUOUS LAYER CONSTITUTED OF A MYRIAD OF DISCRETE NOBLE METAL ISLETS FUSED TO THE SURFACE OF SAID MAGNESIUM OXIDE.
