摘要:

 采用电化学方法制备了对甲基苯磺酸钠掺杂的聚吡咯(TsONa/PPy)锂离子电池正极材料和二氧化钛纳米管阵列 (TiO2NT)负极材料。利用扫描电子显微镜和X射线能量色散光谱仪研究了样品的微观结构及形貌,并进一步组装成全电池,利用恒流充–放电和循环伏安(CV)技术测试了其电化学性能。结果表明:对甲基苯磺酸钠掺杂的聚吡咯正极材料是由直径为  3 μm左右的微球组成,二氧化钛负极材料则呈现三维有序纳米管阵列形貌,两种电极材料的表面皆凸凹不平;由二者组成的全电池首次放电比容量约为105 mA•h/g,经过50次循环后,可逆放电比容量仍保持在65 mA•h/g,表现了良好的循环稳定性,此外还表现了良好的倍率性能。

 Sodium p-toluenesulfonate doped polypyrrole (TsONa/PPy) cathode material and titania nanotube (TiO2NT) arrays anode material for lithium ion battery were synthesized by an electrochemical method. The microstructures and morphologies of the as-prepared sample were investigated by scanning electron microscopy and energy dispersive X-ray spectroscopy. The electrochemical performances of TsONa/PPy/TiO2NT full cell were investigated by galvanostatic charge–discharge and cyclic voltammogram. The results show that TsONa/PPy cathode material consists of many microspheres with the diameter of about 3 μm, and TiO2 anode material appears three-dimensional ordered nanotube arrays with the tough and uneven surfaces. TsONa/PPy/TiO2NT full cell delivers an initial discharge specific capacity of 105 mA?h/g, and the corresponding reversible discharge specific capacity is 65 mA?h/g even after 50 cycles, indicating a good cycle stability. In addition, the full cell also exhibits a good rate performance.
