In this paper, porous partially fluorinated graphene (PFG) for supercapacitors (SCs) was fabricated by a mild and secure one-pot hydrothermal method utilizing weakly coordinating anion BF₄⁻ as the fluorine source. The hydrolysis rate of sodium fluoroborate was adjusted by controlling the reaction temperature and PFG containing semi-ionic CF bonds was obtained, where the content of semi-ionic CF bonds in PFG can be easily regulated. The final experimental results show that the incorporation of fluorine not only modulates the electrochemical properties of the material, but also creates abundant pores. When assembled in a symmetric supercapacitor, the PFG shows a high specific capacitance of 269.7 F g⁻¹ at 1 A g⁻¹ and a superior rate capability with 89.3% capacitance retained, as the current density is increased from 1 A g⁻¹ even to 20 A g⁻¹. Furthermore, the resultant energy density for PFG is 9.4 Wh kg⁻¹ at a power density of 250.0 W kg⁻¹ (1 A g⁻¹). All these results confirm that as-prepared partially fluorinated graphene is appropriate for the application in SCs and mass production.

在本文中，用于超级电容器 (SC) 的多孔部分氟化石墨烯 (PFG) 通过温和且安全的一锅水热法利用弱配位阴离子 BF ₄ ^-作为氟源制备。通过控制反应温度来调节氟硼酸钠的水解速率，得到含有半离子CF键的PFG ，其中PFG中半离子CF键的含量可以很容易地调节。最终的实验结果表明，氟的掺入不仅可以调节材料的电化学性能，而且还会产生丰富的孔隙。当组装在对称超级电容器中时，PFG在 1 A g ^{-1 下}显示出 269.7 F g ^-1的高比电容当电流密度从 1 A g ^-1甚至增加到 20 A g ^{-1 时}，保持了 89.3% 的电容，并具有优异的倍率性能。此外，PFG 的合成能量密度在 250.0 W kg ^-1 (1 A g ^-1 )的功率密度下为 9.4 Wh kg ^-1。所有这些结果证实，所制备的部分氟化石墨烯适用于 SCs 和大规模生产中的应用。
