摘要
为了降低含氟电解液对环境的不良影响和有用资源的浪费,本文以不同使用次数(n≤15)的含氟溶液作为电解液,采用阳极氧化法制备了一系列TiO_2纳米管阵列(TiO_2NT)。然后借助SEM、恒流充/放电、循环稳定性及循环伏安(CV)技术研究了含氟电解液的使用次数(n≤15)对所制备纳米管阵列电极的形貌及脱/嵌锂离子性能的影响。结果表明:含氟电解液的使用次数(n≤15)对TiO_2NT形貌的负面影响不明显;作为锂离子电池负极活性材料时,电化学脱/嵌锂性能也没有出现大幅降低。
In order to decrease the harmful effects of the fluoride-containing electrolyte on the environment and the waste of useful resources, three dimensional ordered TiO2 nanotube arrays (TiO2NT) were prepared via anodization in the recycled fluoride-containing electrolyte (n ≤ 15 ). The effect of cycle number ( n ≤ 15 ) of the fluoride-containing electrolyte on morphology and Li + deinsertion/insertion performances of the as-synthesized TiO2 NT electrodes were investigated in terms of SEM, galvanostatic charge/discharge, cycle stability and cyclic voltammetry (CV). The results show that the cycle number (n≤15) of the fluoride-containing electrolyte has no obvious negative influence on the morphology; and the corresponding electrochemical deinsertion/insertion performances of TiO2 NT anode active material in Li-ion battery doesnt significantly decrease.
