Pristine metal-organic frameworks (MOFs) are built through self-assembly of electron rich organic linkers and electron deficient metal nodes coordinate bond. Due to the unique properties of MOFs like highly tunable frameworks, huge specific surface areas, flexible chemical composition, flexible structures and a large volume of pores, they are being used to design the electrode materials for electrochemical energy storage devices. As per the literature, MOFs (including manganese, nickel, copper, and cobalt-based zeolitic imidazolate frameworks (ZIFs), University of Oslo (UiO) MOFs, Hong Kong University of Science and Technology (HKUST) MOFs and isoreticular MOFs (IRMOFs)) have attracted much attention in the field of supercapacitors (SCs)/batteries. According to their dimensionality such as 1D, 2D and 3D, pristine MOFs are mainly used as SC materials. Highly porous materials and their composites are capable for intercalation of metal ions (Na/Li). Moreover, the supramolecular features (π⋯π, C-H⋯π, hydrogen bond interactions) of redox stable MOFs provide better insight for electrochemical stability. So, this review provides an in-depth analysis of pure MOFs and MOF derived composites (MOF composites and MOF derived porous carbon) as electrode materials and also discusses their metal ion charge storage mechanism. Finally, we provide our perspectives on the current issues and future opportunities for supercapacitor materials.
原始金属有机框架材料（MOFs）是通过富电子有机连接体和缺电子金属节点之间的自组装形成配位键构建而成的。由于MOFs具有独特的性质，如高度可调的框架结构、巨大的比表面积、灵活的化学成分、灵活的结构和大量的孔隙，它们正被用于设计电化学储能装置的电极材料。根据文献记载，MOFs（包括锰、镍、铜和钴基沸石咪唑酯框架材料（ZIFs）、奥斯陆大学（UiO）MOFs、香港科技大学（HKUST）MOFs和同网状MOFs（IRMOFs））在超级电容器（SCs）/电池领域引起了广泛关注。根据其维度，如一维、二维和三维，原始MOFs主要用作超级电容器材料。高孔隙率材料及其复合材料能够嵌入金属离子（钠/锂）。此外，氧化还原稳定的MOFs的超分子特征（π⋯π、C-H⋯π、氢键相互作用）为电化学稳定性提供了更好的见解。因此，本综述对纯MOFs以及MOF衍生复合材料（MOF复合材料和MOF衍生多孔碳）作为电极材料进行了深入分析，并讨论了它们的金属离子电荷存储机制。最后，我们对超级电容器材料当前存在的问题和未来的机遇提出了看法。
