The hydrothermal growth of crystalline β-V2O5 microstructures was performed on fluorine doped tin dioxide glass substrates using oxalic acid to adjust the pH of the solution for various deposition periods. It was observed that the sample grown for 48 h at pH 2 exhibited the best electrochemical response in terms of the highest specific charge and capacitance, being 772 C g(-1) and 386 F g(-1) respectively. The importance of achieving high crystalline quality samples and increased surface area toward the improvement of the electrochemical performance of β-V2O5 is highlighted.
在掺氟二氧化锡玻璃基板上，使用草酸调节溶液的pH值，在不同沉积时间下进行了结晶β-V2O5微结构的水热生长。观察到，在pH值为2的条件下生长48小时的样品，在比电荷和电容方面表现出最佳的电化学响应，分别为772 C g(-1)和386 F g(-1)。强调了获得高质量结晶样品和增加表面积对改善β-V2O5电化学性能的重要性。
