通过阳极氧化、电沉积和450℃下的热氧化，设计并合成了高性能的无粘结剂四元复合CuO/Cu/TiO2纳米管/钛(CuO/Cu/TiO2NT/Ti)锂离子电池电极。用X射线衍射仪、X射线光电子能谱、扫描电子显微镜、能谱分析、恒流充放电、循环稳定性、循环伏安和交流阻抗等方法对制备的无粘结剂CuO/Cu/TiO_2NT/Ti四元复合电极进行了研究。如预期的那样，无粘结剂的CuO/Cu/TiO2NT/Ti四元复合电极的放电容量、循环稳定性、Li+扩散系数都比裸TiO2NT/Ti电极高得多。CuO的高储锂活性、铜的高电导率以及各组分之间的协同作用是提高电化学性能的原因。此外，由于排除了聚合物粘结剂的负面影响，各种组分的无粘结剂组合也可能有助于改性。
High performance binder-free quaternary composite CuO/Cu/TiO2nanotube/Ti (CuO/Cu/TiO2NT/Ti) electrode for lithium ion battery was designed and synthesized via anodization, electrodeposition and thermal oxidation at 450 °C in the air. The as-prepared binder-free quaternary composite CuO/Cu/TiO2NT/Ti electrode was studied in terms of XRD, XPS, SEM, EDX, galvanostatic charge/discharge, cycle stability, cyclic voltammetry (CV) and AC impedance. As expected, the binder-free quaternary composite CuO/Cu/TiO2NT/Ti electrode displayed much higher discharge capacity, cycle stability, Li+diffusion coefficient than bare TiO2NT/Ti electrode. High Li-storage activity of CuO, high conductivity of Cu and the synergy effect among various components should be responsible for improved electrochemical performances. Additionally, binder-free combination of the various components may also contribute into the modifications due to the exclusion of negative effect of polymer binder.
