铅酸电池调研初步;铅酸电池的工作原理;;铅酸电池的优缺点; Plante1859年发明铅酸电池 Faute用红铅涂在铅板上，法兰绒为分隔层，电池容量提高。 Brush发现了在铅板上多孔涂层的重要性。 1881 年，Volkmann 申请了带孔铅板的专利。 J.S.Sellon使用了铅锑合金使活性物质在的附着性能更好，同时提高了铅板的强度，。 目前板栅主要采用Pb-Sb，Pb-Ca，Pb-Sb-As等合金 采用不同的合金，以期达到较好的抗腐蚀性能。 泡沫铅可提高电池活性物质的利用率和质量比容量 导电聚合物，石墨材料等材料构筑板栅;Journal of Power Sources 158 (2006) 885–890;铅氧纳米材料的制备及其在铅酸电池方面的应用;目前常见制备这些氧化物活性物质的办法包括溶胶凝胶法，机械球磨发 高温化学方法。但目前主要集中在球状的，无定形的 且结晶较差。另外氧化铅的前驱体，以及溶液合成量少 。但以化学手段合成的氧化铅同电化学手段合成的纳米氧化铅粉末相比，其电化学性质按目前的报道来看，是比较差的。但是，由于氧化铅材料的纳米化可以显著的提高其比表面积，通过电化学合成的氧化铅可能具有较好的电化学性能。 ;Journal of Power Sources 191 (2009) 36–41;使用前; J Alloy Compd 327 (2001) 141 –145;lead oxide nano-powder (a) conventional leady oxide powder. (b) ;Nevertheless, there are only few reports on the synthesis of lead oxide in nano-scale. A number of electrochemical techniques have been used to prepare lead dioxide some of which are constant current and constant potential, cyclic voltammetry and pulse current methods. Shen and Wei deposited lead dioxide from a solution containing Pb2+ on three different substrates (i.e. Au, Pt and Ti) with different techniques. Konstantinov et al. used the spray pyrolysis method for synthesis of nanostructured lead oxide. They had a systematic study of the effect of various spray pyrolysis parameters such as temperature, solution concentration and solution flow rate on the morphology, crystallization process, crystal size and specific surface area. They synthesized globular shape lead oxide in the wide range of particle size of 20–127?nm There are many reports on the effect of ultrasonic waves on morphology and particle size in synthesized solutions. In many reports, the ultrasonic-affected synthesized solution is called Sonochemical solution while the method used for synthesis being called “Sonochemical method”. The ultrasonic affect on synthesized system in many ways is strongly dependent on system species and reaction mechanism. Zhang et al. have reported that the Sonochemical method is an effective way of stabilizing the
