    摘要: A metal separator for a fuel cell of the present invention includes a metal substrate having a reactant flow pathway, and a metal nitride coating layer. The metal nitride coating layer covers the surface of the metal substrate on which a reactant flow pathway is formed and slurry-coated. A metal layer for improving adherence is formed between the surface of the metal substrate on which a reactant flow pathway is formed, and the electro-conductive metal nitride coating layer. The metal separator is suitable for a fuel cell since it is lightweight, and has excellent anti-corrosion and electric conductivity.

    摘要: A process of manufacturing a positive active material for a lithium secondary battery includes adding a metal source to a doping element-containing coating liquid to surface-treat the metal source, wherein the metal source is selected from the group consisting of cobalt, manganese, nickel, and combination thereof; drying the surface-treated metal source material to prepare a positive active material precursor; mixing the positive active material precursor with a lithium source; and subjecting the mixture to heat-treatment. Alternatively, the above drying step during preparation of the positive active material precursor is substituted by preheat-treatment or drying followed by preheat-treatment.
