Supercapacitors (SCs) have been widely investigated in the realm of energy resulting from their superior long lifespan and remarkable power density. However, their practical usage is limited because of the high effective resistance and relatively low energy density. Electrode material is crucial for determining the performance of SCs, so the innovation and development of advanced electrode materials is particularly important. Metal-organic frameworks (MOFs) and carbonaceous materials, including MOF-derived carbons and carbon nanotubes (CNTs), are befitting as electrode active materials for SCs on the strength of the unique features of high porosity, tunable structures, and easy formation of composites with other compounds. Hence, great efforts were devoted on the synthesis strategies and structural modifications of electrodes to enhance the performance of SCs. In this review, the recent innovations in the realm of SCs, including the application of pristine and derivatives of MOFs as SC electrode materials, were extensively studied. Furthermore, the functions and electrochemical performance of various MOFs and their derivatives (e.g., MOF-derived carbons) were analyzed accordingly. Lastly, the innovations and application of CNTs as SC electrode active materials are systematically summarized. This review highlights the electrochemical performance of some advanced MOF- and carbon-based materials, and the critical factors for SC electrode active materials to achieve excellent electrochemical performance in the application of energy storage systems.

Hydrothermal Approach

Electrochemical performance of the material depends on the morphology and structural characteristics of the material. Co3O4 samples shows the remarkable electrochemical performance owing to the high porosity, appropriate pore size distribution and novel architecture and reaction time effect of morphology. In this work, Co3O4 nanowires grown on Ni foam have been synthesized through a facile hydrothermal approach, revealing large capacitance of 2178.4 mF cm-2 at the current density of 2 mA cm-2 and cycling stability with 79.6% capacitance retention after 6000 cycles. The as-assembled device delivers excellent electrochemical performance for high specific capacitance of 356 mF cm-2 at the current density of 2 mA cm-2 and high cycle stability.

Cu-N-C electrocatalyst was successfully prepared with Cu-BTC and polyacrylonitrile as templates by electrospinning and in-situ growth method. The effect of various [Formula: see text]-doped content on the electrochemical performance of the catalyst were investigated and the Cu-N-C-0.25 exhibited the best OER/ORR catalytic activities. When it was applied to the cathode of the zinc-air batteries, the power density of Cu-N-C-0.25 was 209.1[Formula: see text]mW[Formula: see text]cm[Formula: see text], which exceeded that of the commercial Pt/C[Formula: see text]IrO2 hybrid catalyst (157[Formula: see text]mW[Formula: see text]cm[Formula: see text]). The excellent electrochemical performance may be attributed to large number of active sites and high specific surface area on Cu-N-C electrocatalyst. It will be a promising alternative to precious metal catalysts containing Pt, Ir or Ru and their oxides.
