摘要：As the positive active material of lead acid battery, microstructure and surface morphology of PbO2have a strong influence on the electrochemical performance. Nanostructured PbO2microspheres were prepared by a simple solution method with cetyltrimethylammonium bromide as a structure-directing agent. The thin positive electrode of lead acid battery was prepared by pressing the nanostructured PbO2microspheres onto a lead alloy sheet. Furthermore, the as-prepared PbO2microspheres delivered a discharge capacity of 101.8 mAh/g (45% of active material utilization) and displayed a good cycle life. It is believed that the special morphology plays a vital role in the enhancement of discharge performance. © 2012 Elsevier B.V.
