An efficient cathodic electrodeposition method is developed for coating Co-based metal-organic frameworks (Co-MOF) on carbon fiber cloth (CFC), a widely used substrate in energy fields. The use of a highly active Co metal surface enables nucleation and growth of Co-MOF in 3D rodlike crystal bundles. When used as a binder-free electrode (Co-MOF/CFC) for supercapacitors, it shows a high areal capacitance of 1784 mF cm at 1 mA cm , good cycling stability and excellent rate capability. The assembled asymmetric all-solid-state supercapacitor device (Co-MOF/CFC//AC) delivers a high energy density and power density. This work may open up an effective approach to realize the electrosynthesis of MOF films, promoting use in energy storage and conversion fields.
开发了一种高效的阴极电沉积方法，用于在碳纤维布（CFC）上涂覆钴基金属有机框架（Co-MOF），CFC是能源领域广泛使用的基底。高活性钴金属表面的使用使得Co-MOF能够在三维棒状晶体束中形核并生长。当用作超级电容器的无粘结剂电极（Co-MOF/CFC）时，在1 mA cm下显示出1784 mF cm的高面积电容、良好的循环稳定性和优异的倍率性能。组装的不对称全固态超级电容器器件（Co-MOF/CFC//AC）具有高能量密度和功率密度。这项工作可能开辟一种实现MOF薄膜电合成的有效方法，促进其在能量存储和转换领域的应用。
