摘要：

Silica and its compounds have attracted considerable attention because they own some unique features like great electrochemical stability in sulfuric acid solution and strong electrolyte storage capacity. In this paper, SiO2+PbO2 powders with high specific surface area, hierarchical porous structure and good electrochemical performance have been prepared successfully via the facile anode co-electrodeposition. After adding these powders into the lead-carbon battery, this additive can build outstanding ion transfer channels inside the positive active material and thus advance the energy density and stability of the positive electrode via the enhancement of ionic diffusivity and the promotion of contact between ion and electrode. Comparing with the lead-carbon battery without this additive, the energy density of the modified battery is increased by 12% and the stability is enhanced by 10% after cycling 3000 times in HRPSoC.
