“…The as-synthesized Ni/MOF gives two distinct diffraction patterns at 9.7 and 22.2° corresponding to the Miller indices of Ni-MOF (100) and Ni-MOF (101), respectively. 25 , 28 These characteristic peaks are a clear indication for the complete synthesis of the as-synthesized Ni-MOF, and similar diffraction patterns have previously been reported for Ni-based MOFs. 29 − 31 After annealing at high temperature, the frameworks of the as-synthesized Ni-MOF decomposed to produce nickel nanoparticles-supported MOF-derived carbon (Ni/MOFDC) with different diffraction patterns observed at 26.3, 44.9, 52.1, 76.7, 93.1, and 98.5°, attributable to broad hexagonal graphitic carbon, MOFDC (002), Ni(111), Ni(200), Ni(220), Ni(311), and Ni(222), respectively.…”

A Ni-based metal–organic framework (Ni-MOF) has been synthesized using a microwave-assisted strategy and converted to nanostructured Ni/MOF-derived mesoporous carbon (Ni/MOFDC) by carbonization and acid treatment (AT-Ni/MOFDC). The materials are well characterized with Raman, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and Brunauer–Emmett–Teller (BET), revealing that chemical etching confers on the AT-Ni/MOFDC-reduced average nanoparticle size (high surface area) and structural defects including oxygen vacancies. AT-Ni/MOFDC displays low series resistances and a higher specific capacity ( C s ) of 199 mAh g –1 compared to Ni/MOFDC (92 mAh g –1 ). This study shows that the storage mechanism of the Ni-based electrode as a battery-type energy storage (BTES) system can be controlled by both non-faradic and faradic processes and dependent on the sweep rate or current density. AT-Ni/MOFDC reveals mixed contributions at different rates: 75.2% faradic and 24.8% non-faradic contributions at 5 mV s –1 , and 34.1% faradic and 65.9% non-faradic at 50 mV s –1 . The full BTES device was assembled with AT-Ni/MOFDC as the cathode and acetylene black (AB) as the anode. Compared to recent literature, the AT-Ni/MOFDC//AB BTES device exhibits high energy (33 Wh kg –1 ) and high power (983 W kg –1 ) with excellent cycling performance (about 88% capacity retention over 2000 cycles). This new finding opens a window of opportunity for the rational designing of next-generation energy storage devices, supercapatteries, that combine the characteristics of batteries (high energy) and supercapacitors (high power).

“…The CFC displays no capacitance contribution to the electrode (ref) but constitutes a 3D channel that enables smooth migration of electrons and ions, and further facilitates direct connection with VN interlaced nanowires. Furthermore, it has been already justified that phase boundaries between the lattice fringes of two electrodes constructing an angular mismatch are avenues for accommodating additional Li ion [ 72 , 73 , 74 ]. The interfaces between the (200) plane of VN and (002) plane of MoS 2 will generate additional storage capacitance, also leading to high capacitance of the synergistic VN/MoS 2 hybrid.…”

Vanadium nitride (VN) shows promising electrochemical properties as an energy storage devices electrode, specifically in supercapacitors. However, the pseudocapacitive charge storage in aqueous electrolytes shows mediocre performance. Herein, we judiciously demonstrate an impressive pseudocapacitor performance by hybridizing VN nanowires with pseudocapacitive 2D-layered MoS2 nanosheets. Arising from the interfacial engineering and pseudocapacitive synergistic effect between the VN and MoS2, the areal capacitance of VN/MoS2 hybrid reaches 3187.30 mF cm−2, which is sevenfold higher than the pristine VN (447.28 mF cm−2) at a current density of 2.0 mA cm−2. In addition, an asymmetric pseudocapacitor assembled based on VN/MoS2 anode and TiN coated with MnO2 (TiN/MnO2) cathode achieves a remarkable volumetric capacitance of 4.52 F cm−3 and energy density of 2.24 mWh cm−3 at a current density of 6.0 mA cm−2. This work opens a new opportunity for the development of high-performance electrodes in unfavorable electrolytes towards designing high areal-capacitance electrode materials for supercapacitors and beyond.
