“…On the other hand, carbon-based current collector such as CFP is rather stable in all electrolytes [9][10][11][12][13]. CFP has many advantages suitably to be used as the conductive substrate or current collector including high flexibility, corrosive resistance, porosity, and conductivity.…”

“…However, CFP consisting of sp 2 carbon fiber (90-95 wt.%) and adhesive material PTFE (5-10 wt.%) can be used only as a conductive current collector since it cannot store charge and its hydrophobic surface in nature, which cannot adsorb/absorb the aqueous electrolyte. CFP is therefore used as the conductive substrate and/or current collectors of the supercapacitors and fuel cells [9][10][11][12][13].…”

“…33 Further, M. Du reported a mesoporous In-based MOF material with 1-D hexagonal channels, which provided a capacitance of 81 F g À1 (1 A g À1 ) and maintain about 100% of its maximum value aer cycling 6000 times. 39 Though the method was relatively effective to improve the electrical properties of MOFs, it was cumbersome and complicated. 35 Obviously, the above MOFs materials have had limited success in supercapacitor.…”

A hybrid material of carbon nanotubes (CNTs) and Mn-based metal organic frameworks (Mn-MOF) was synthesized and used as a Mn-based supercapacitor electrode material. The incorporation of CNTs into Mn-MOF led to an inherent improvement in conductivity and an intrinsic increase in specific capacitance (from 43.2 F g À1 for pure Mn-MOF to 203.1 F g À1 for CNTs@Mn-MOF). Furthermore, the symmetrical supercapacitor based on the CNTs@Mn-MOF exhibited excellent power density and outstanding stability even after 3000 cycles with 88% retention of the initial capacitance. This research exploited a new direction for developing Mn-based supercapacitor materials and provided an effective method to improve capacitive performance of MOFs materials.

“…10–50 nm due to the interconnection of the MnO 2 nanosheets. This morphology is ideal for the supercapacitor electrode since it can enhance the mass transport of the electrolyte due to the capillary force2930. Figure 1b shows an FE-SEM image of N-rGO ae illustrating a few layers of overlapping graphene sheets forming the framework structure with a pore diameter of 0.2–3 μm.…”

Although manganese oxide- and graphene-based supercapacitors have been widely studied, their charge storage mechanisms are not yet fully investigated. In this work, we have studied the charge storage mechanisms of K-birnassite MnO2 nanosheets and N-doped reduced graphene oxide aerogel (N-rGOae) using an in situ X-ray absorption spectroscopy (XAS) and an electrochemical quart crystal microbalance (EQCM). The oxidation number of Mn at the MnO2 electrode is +3.01 at 0 V vs. SCE for the charging process and gets oxidized to +3.12 at +0.8 V vs. SCE and then reduced back to +3.01 at 0 V vs. SCE for the discharging process. The mass change of solvated ions, inserted to the layers of MnO2 during the charging process is 7.4 μg cm−2. Whilst, the mass change of the solvated ions at the N-rGOae electrode is 8.4 μg cm−2. An asymmetric supercapacitor of MnO2//N-rGOae (CR2016) provides a maximum specific capacitance of ca. 467 F g−1 at 1 A g−1, a maximum specific power of 39 kW kg−1 and a specific energy of 40 Wh kg−1 with a wide working potential of 1.6 V and 93.2% capacity retention after 7,500 cycles. The MnO2//N-rGOae supercapacitor may be practically used in high power and energy applications.
