As many countries begin to approach legislation to control carbon dioxideemissions,combined with the continuing rise in oil-based fuel prices, hybrid electricvehicles (HEVs) begin to be used in the automotive market place. Compare to leadacid battery, Pb-C battery has low cost, and long life especially under the HRPSOCmode which suitable for hybrid vehicles.The influence of the addition of carbon to the cycling performance of Pb electrodehas been studied firstly. The results indicated that the concentration of carbon has agreat impact on the cycling performance of electrode. Electrode with CB1、AC1orCNTs display the excellent cycling performanceIn order to obtained a better performance of electrode,the composite carbonmaterials with CB1、AC1and CNTs were prepared. When the electrode had theexcellent cycling performance with completing11090HRPSoC micro-cycles in thefirst cycle-set, the concentration of CB1is0.2%and CNTs is1.0%. Comparision ofthe Pb-C electrode with the traditional commercial electrode indicated that thedischarge capacity of the Pb-C electrode is almost the same with CE electrode but hasbetter cycling performance and better discharge performance at high rate.By comparing the effect of two adhesive in the performance of electrode, theCMC not only influenced the discharge capacity of electrode, but also seriouslyaffected the cycle performance of the electrode, while the PTFE did not affect thedischarge capacity of electrode, but reduced on the cyclic performance slightly.In order to reduce the hydrogen evolution rate of Pb-C electrode,carbonmaterials were modified by Bi2O3and In2O3with mechanical mixing. Theperformance of electrode evidence that Bi2O3can inhibit the hydrogen evolution rate ofthe electrode, but reduced the cyclic performance. The amount of In2O3not only cansignificantly reduce the hydrogen evolution rate of electrode, but also increase thecycling performance of the electrode. Carbon materials were modified by Bi、In、Agand Sn with reduction method. The results ensured that modified with In and Snwere able to reduce the hydrogen evolution rate of electrode, and also be able toincrease the HRPSoC cycle number of the electrode completed. The electrode whichdeposition of In in the first cycle-set can complete the14793times a loop while theelectrodes deposition of Sn were able to complete25085times cycle. A preliminary study found that the capacitance properties of carbon materialscontribution to the electrode capacity can be negligible, but it increased the hydrogenevolution rate of electrode.By observing the microscopic structure of the electrode, theconductive network of carbon composite material was the reason that the electrode hadthe best performance, and this has been confirmed by the test of resistivity.
