Compared to traditional metal oxides, metal-organic frameworks exhibit excellent properties, such as a high surface area, significant thermal stability, low density, and excellent electrochemical performance. Here, a simple process is proposed for the fabrication of rod-like vanadium metal-organic frameworks (V (O)(bdc), bdc = 1,4-benzenedicarboxylate, or MIL-47), and the effect of the structure on the electrochemical performance is investigated via a series of electrochemical measurements. The V (O)(bdc) electrode exhibits a maximum specific capacitance of 572.1 F g at current densities of 0.5 A g . More significantly, aqueous and solid-state asymmetric supercapacitors are successfully assembled. The solid-state device shows an excellent energy density of 6.72 mWh cm at a power density of 70.35 mW cm . This superior performance confirms that V (O)(bdc) electrodes are promising materials for applications in supercapacitors.

“…It is found by the calculation that the ASC device can achieve a high energy density of 35.4 Wh kg −1 when the power density is 800.0 W kg −1 (Figure f). Compared to the previous reports, such as MnOOH/NiAl‐LDH//activated carbon (AC) ASC (26.89 Wh kg −1 at 800 W kg −1 ), NiCo 2 S 4 //AC ASC (24.78 Wh kg −1 at 1770.13 W kg −1 ), NiCo 2 O 4 @Co−Fe LDH//AC (28.94 Wh kg −1 at 950 W kg −1 ) and Ni−MOF//AC (31.5 Wh kg −1 at 800 W kg −1 ), the ASC in our work is more competitive. What's more, the practical application of the AC//NiAl‐LDH‐0.5/Ni−MOF/S10 ASC has been further evaluated, as shown in the inset of Figure f.…”

Designing nanocomposites with good electrochemical properties is the key to studying electrode materials for supercapacitors. In this paper, we report a well‐defined composite (NiAl‐LDH/Ni−MOF/S) prepared in three steps. After the synthesis of LDH nanoplates through a hydrothermal method, the MOF nanosheets were grown on its surface by in situ nucleation. In this procedure, the synergistic effect of MOF and LDH will improve the specific capacitance. Afterwards, the composite was subjected to a sulfidation treatment to enhance its electrical conductivity. Consequently, the NiAl‐LDH/Ni−MOF/S has an excellent specific capacitance (1670 F g−1 at 1 A g−1) and rate capability (65 % from 1 to 30 A g−1). Moreover, an asymmetric supercapacitor (ASC) was assembled with NiAl‐LDH/Ni−MOF/S as cathode and activated carbon as anode. The ASC displays a maximum energy density (35.4 Wh kg−1) and outstanding cycle stability (retention of 96.4 % after 10000 cycles at 10 A g−1), demonstrating the potential of the electrode for use in high‐efficiency electrochemical capacitors.
