中文摘要:
      目的 提高锂离子电池TiO2负极的电化学性能。方法 采用微弧氧化技术在钛箔表面制备TiO2膜,再通过磁控溅射技术在TiO2膜上沉积Si/SiO2,制备出一种富含硅元素的微弧氧化复合膜。将该复合膜作为锂离子电池负极,锂片为对电极,组装电池。采用电池测试系统测量电池容量、循环稳定性等性能,通过电化学工作站获得循环伏安曲线、电化学阻抗谱等特性。结果 复合膜的组成为TiO2/SiO2/Si,呈现多孔状形貌。TiO2、SiO2和Si都参与了与锂离子的氧化还原反应,在100 μA/cm2的电流密度下,经100圈循环后,复合膜负极的比容量保持在530 (mA.h)/g左右,且在1000 μA/cm2的大电流密度条件下,充放电后,复合膜负极的比容量能够恢复到初始值的95%,表现出较高的比容量、良好的循环稳定性和倍率性能,复合膜负极性能明显优于以纯TiO2为负极的锂离子电池。结论 在钛箔表面,微弧氧化技术可高效地制备多孔状、无粘结剂的TiO2负极材料,与磁控溅射技术相结合,可进一步制备出高容量的复合膜负极,具有良好的应用前景。
英文摘要:
      The aim of this research is to improve the electrochemical performance of the TiO2 anode of lithium-ion battery (LIB). The micro-arc oxidation technology was employed to prepare a TiO2 film on the Ti foil, and then Si/SiO2 was deposited on the TiO2 film by magnetron sputtering technology to prepare a silicon-containing micro-arc oxidation composite film. This composite film was used as the anode of the LIB and a Li foil was used as the counter electrode. The capacity, cycling stability, cyclic voltammetry curves and electrochemical impedance spectra were measured by the battery test system and electrochemical workstation. The experimental results showed that the composite film was composed of TiO2/SiO2/Si with a porous morphology. TiO2, SiO2 and Si all participated in the redox reactions with Li+. After 100 cycles under a current density of 100 μA/cm2, the capacity remained at about 530 (mA.h)/g. Moreover, after cycling under a high current density of 1000 μA/cm2, the capacity can come back to 95% of the initial capacity. This suggests that the prepared TiO2/SiO2/Si composite film has an excellent rate capability with stable structural retention, and its electrochemical performance is much better than that of the TiO2 anode. Therefore, the micro-arc oxidation technology can produce porous and binder-free TiO2 anode materials on the surface of titanium foil with high efficiency. It can also combine with the magnetron sputtering technology to prepare high capacity composite film anodes, which has a bright prospect of industrial application.
