The present invention discloses a method for making lead-carbon electrode sheets, electrode sheet cassette and lead-carbon battery. The method includes of steps of: oxidizing lead under low-temperature atmosphere; and using a specialized ventilation method for the carbon to coat the oxidized lead. The interface layer of oxidized lead forms a stable interface between the carbon and the lead. Meanwhile, through controlling pressure and temperature, a multi-porous metal composite is formed and the porosity can be penetration paths for air and liquid when the multi-porous metal composite is applied. The lead-carbon composite is applied as a lead-carbon electrode sheet and is further welded as a lead-carbon electrode sheet of a lead-carbon battery. The lead-carbon battery carrying the lead-carbon electrode demonstrates Coulomb efficiency of 100% without heat loss on an unsaturated charge-discharge condition, demonstrating high-efficiency charging and discharging.
