To satisfy the ever-increasing energy demands, it is of the utmost importance to develop electrochemical materials capable of producing and storing energy in a highly efficient manner. Titanium dioxide (TiO) has recently emerged as a promising choice in this field due to its non-toxicity, low cost, and eco-friendliness, in addition to its porosity, large surface area, good mechanical strength, and remarkable transport properties. Here, we present titanium dioxide nanoplates/polyvinylidene fluoride (TiO/PVDF) membranes prepared by a straightforward hydrothermal strategy and vacuum filtration process. The as-synthesized TiO/PVDF membrane was applied for energy storage applications. The fabricated TiO/PVDF membrane served as the negative electrode for supercapacitors (SCs). The electrochemical properties of a TiO/PVDF membrane were explored in an aqueous 6 M KOH electrolyte that exhibited good energy storage performance. Precisely, the TiO/PVDF membrane delivered a high specific capacitance of 283.74 F/g at 1 A/g and maintained capacitance retention of 91% after 8000 cycles. Thanks to the synergistic effect of TiO and PVDF, the TiO/PVDF membrane provided superior electrochemical performance as an electrode for a supercapacitor. These superior properties will likely be used in next-generation energy storage technologies.
为了满足不断增长的能源需求，开发能够高效生产和储存能源的电化学材料至关重要。由于其无毒、低成本、环保，以及多孔性、大表面积、良好的机械强度和卓越的传输性能，二氧化钛 (TiO) 最近成为该领域的有前途的选择。在这里，我们提出了通过简单的水热策略和真空过滤工艺制备的二氧化钛纳米板/聚偏二氟乙烯 (TiO/PVDF) 膜。所合成的 TiO/PVDF 膜应用于储能应用。制备的 TiO/PVDF 膜用作超级电容器 (SCs) 的负极。在含有 6 M KOH 电解质的水性电解质中探索了 TiO/PVDF 膜的电化学性能，表现出良好的储能性能。具体而言，TiO/PVDF 膜在 1 A/g 时表现出 283.74 F/g 的高比电容，并在 8000 次循环后保持 91%的电容保持率。由于 TiO 和 PVDF 的协同效应，TiO/PVDF 膜作为超级电容器的电极提供了卓越的电化学性能。这些优异的性能可能会用于下一代储能技术。
