“…Therefore, various 3D MOF nanostructures, such as flowers and honeycombs, have been integrated with conductive substrates. As a typical example of self-supported 3D MOF electrodes, Chen et al 50 fabricated a porous Ni/Co based MOF with a honeycomb structure directly on carbon cloth (Ni/Co-MOF@CC) though a hydrothermal method using H 32 Mo 7 N 6 O 28 as a catalyst. The good electrical conductivity and the porous wasp-like structure endowed the Ni/Co-MOF@CC electrode with good electrochemical properties.…”

“…Therefore, researchers combined MOFs with highly conductive carbon-based materials such as RGO, CNT, and C 3 N 4 . [454][455][456] What is more, in 2016, Sheberla and co-workers prepared a highly electrical conductivity MOF of Ni 3 (HITP) 2 (Ni 3 (2,3,6,7,10,11-hexaiminotriphenylene) 2 ), which can directly be used as an EDLC electrode material. The Ni 3 (HITP) 2 is built of stacked π-conjugated 2D layers, which are penetrated by 1D cylindrical channels of ≈1.5 nm diameter.…”

Asymmetric supercapacitors (ASCs) can substantially broaden their working voltage range, benefiting from the advantages of both cathode and anode while breaking through the energy storage limitations of corresponding symmetric cells. Wide voltage aqueous ASCs hold great promise for future electronic systems that require satisfied energy density, power density, and cycle life, due to the advantages of aqueous electrolyte in terms of low cost, operational safety, facile manufacture, environment-friendly, and high ionic conductivity. This review will first briefly present an overview of the historical developments, charge storage mechanisms, and matching principles of wide voltage aqueous ASCs. Then, the cathode and anode materials with wide potential windows for building wide voltage aqueous ASCs over the last few decades are summarized. The next section details the optimization methods of aqueous electrolyte related to wide voltage aqueous ASCs. In addition, the basic device configurations of wide voltage aqueous ASCs are classified and discussed. Furthermore, several strategies are proposed for achieving highperformance wide voltage aqueous ASCs in terms of voltage window, specific capacitance, rate performance, and electrochemical stability. Finally, to motivate further research and development, several key scientific challenges and the perspectives are discussed.

“…The cycling stability in both three‐ and two‐electrode system is estimated with the capacitance retention after a specific charge‐discharge cycle number by either CV or GCD method. However, in a few cases, especially those for battery‐SC hybrid applications, the authors only reported the specific capacity (in C g −1 /C cm −2 /C cm −3 or mAh g −1 /mAh cm −2 /mAh cm −3 ) of the electrode materials based on metal‐organic compounds 25‐39 . Considering that the specific capacitance is the parameter reported in the most research papers of SC discipline, those literatures which only reported the specific capacity of transition metal‐organic compounds of the first transition metal series as SC electrode materials are not included in this review.…”

Metal‐organic compounds, including molecular complexes and coordination polymers, have attracted much attention as electrode materials in supercapacitors owing to their large surface area, high porosity, tailorable pore size, controllable structure, good electrochemical reversibility, and abundant active sites. Among the variety of metal‐organic compounds exhibiting desired supercapacitor performances (high specific capacitance, long cycling life, high energy density, and power density), those with metals in the first transition metal series are the most studied due to their rich covalent states, light atom weight, environmental‐friendliness, non‐toxicity, and low cost. In this review, the recent reports on the metal‐organic compounds of the first transition metal series as electrode materials in supercapacitors are summarized and their electrode and device performances are discussed in terms of different metal elements and typical multidentate ligands. Moreover, the current challenges, design strategies, future opportunities and further research directions are also highlighted for metal‐organic compounds in the field of supercapacitors.
