摘要:
聚苯胺有良好的导电性、氧化还原可逆性且制备合成简单易得,是二次可充电池的理想正极材料.泡沫镍因其三维多孔结构,有较大的比表面积,有助于提高活性物质负载量,相比传统膜电极,泡沫镍电极具有更大的放电电流密度.防止了泡沫镍基体的腐蚀,将聚苯胺粉末配成悬浮溶液采用阴极电泳法在泡沫镍基体上沉积聚苯胺修饰层.然后用真空抽滤灌注的方式将聚苯胺浆液填充到泡沫镍孔隙中,泡沫镍基聚苯胺电极的电化学储能性能有了明显的改善,电极活性物质与基体接触的更紧密,接触电阻减小,极化也减小.在醋酸锌-醋酸锂电解液体系中,泡沫镍基聚苯胺电极基体有很好的抗腐蚀性能,并且聚苯胺能够保持较高的电化学活性.5 mA/cm2电流充放电库伦效率在充放电30 次以后仍能在90% 以上.该体系具有良好的循环特性,具有实际的应用前景.
Abstract:
Due to its good conductivity,easy preparation and oxidation-reduction reversibility,polyaniline become the ideal cathode material of secondary rechargeable battery.Nickel foam has a larger specific surface area,and can help to increase the mass of active material because of its three-dimensional porous structure.Compared with traditional membrane electrode,nickel foam supported polyaniline electrode has a larger discharge current density.The cathode electrophoresis is applied to the fabrication of Ni foam supported PANI electrode,in which the corrosion of the nickel foam substrate is prohibited.The polyaniline slurry was then filled into the pores of the foamed nickel by means of vacuum filtration and perfusion,the electrochemical charge storage performance for PANI material is significantly improved by using nickel foam substrate via the electrophoresis interlayer,the electrode active material contact more closely with the matrix,contact resistance decreases,polarization decreases.In the zinc acetate-acetic acid Lithium electrolytic system,the corrosion problems of nickel foam electrode substrate have improved significantly,and the polyaniline still keep high electrochemical activity.The Coulombic efficiency can still be over 90% after 30 times charge and discharge cycles at the working current of 5 mA·cm-2. The system indicates pretty cycle performance and the practical application prospect.
