| Abstract: | A new type porous foamed lead electrode is fabricated by penetration casting method. The scanning images show three dimensional framework and ideal netted structure. The electrode structure parameters, such as porosity, pore diameter, density, compressive strength and the compositions after lead electrode being discharged are measured and quantitatively analyzed. By simulated experiments of the porous foamed lead electrode in battery, the factors of electrode pore diameter size and surface chemical treatment, which affect discharging property, are investigated. The results lay the foundation of investigating light electrode material of high energy density and long lifetime. |
