  • Patent number: 11349110
    Abstract: The present disclosure discloses a method for forming a lead-carbon compound interface layer on a lead-based substrate, wherein the lead-based substrate has a surface, and the method includes steps of: causing an acidic solution to contact with a carbon material and a lead-containing material to form a carbon-containing plumbate precursor having an ionic lead; and reducing the ionic lead in the carbon-containing plumbate precursor to form the lead-carbon compound interface layer on the surface.
    Type: Grant
