  • Method for forming lead-carbon compound interface layer on lead-based substrate
    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
    Filed: January 13, 2020
    Date of Patent: May 31, 2022
    Assignee: NATIONAL FORMOSA UNIVERSITY

  • Methods for making lead-carbon couplings, lead-carbon electrode sheets and lead-carbon batteries
    Patent number: 10361420
    Abstract: Methods for making lead-carbon coupling, lead-carbon electrode sheets, and a lead-carbon battery are revealed. The coupling methods consist of steps of assembling the carbon material that contains oxygen functional groups or metal precursors and lead material in contact with each other and then heating the assembled lead-carbon pair to form lead oxides or metal carbides as a bridge to form coupled lead-carbon interface with high electrochemical and mechanical stability. This coupled lead-carbon structure is applied to form lead-carbon electrode sheets and is further used as electrode sheets of lead-carbon batteries by lead welding.
