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.
