“…In addition, conventional electrode preparation methods require the incorporation of a binder and an active material on the collector, which is detrimental to the improvement in electrochemical performance [16,17]. The three-dimensional porous nickel foam used as the substrate for electrodeposition has a higher active material loading mass compared to the conventional planar substrate, and the three-dimensional structure of the nickel foam substrate can also shorten the ion transmission distance and provide a highly conductive network.…”

“…The three-dimensional porous nickel foam used as the substrate for electrodeposition has a higher active material loading mass compared to the conventional planar substrate, and the three-dimensional structure of the nickel foam substrate can also shorten the ion transmission distance and provide a highly conductive network. For the electrodeposition method, the main current research focuses on different deposition methods and different voltages and currents [16][17][18], and in fact, the concentration of precursors also has a great effect on electrodeposition, as it is necessary to study the effect of precursor concentration on electrodeposition.…”

In this work, we used the mixed solution of manganese acetate and sodium sulfate to deposit manganese dioxide on the three-dimensional porous nickel foam that was previously soaked in alcohol, and then the effects of solution concentrations on their capacitance properties were investigated. The surface morphology, microstructure, elemental valence and other information of the material were observed by scanning electron microscope (SEM), Transmission Electron Microscope (TEM), X-ray photoelectron spectroscopy (XPS), etc. The electrochemical properties of the material were tested by Galvanostatic charge-discharge (GCD), Cyclic Voltammetry (CV), Chronoamperometry (CA), Electrochemical impedance spectroscopy (EIS), etc. The MnO2 electrode prepared at lower concentrations can respectively reach a specific capacitance of 529.5 F g−1 and 237.3 F g−1 at the current density of 1 A g−1 and 10 A g−1, and after 2000 cycles, the capacity retention rate was still 79.8% of the initial capacitance, and the energy density can even reach 59.4 Wh Kg−1, while at the same time, it also has a lower electrochemical impedance (Rs = 1.18 Ω, Rct = 0.84 Ω).

“…A classical supercapacitor includes electric double‐layer capacitors arising from ion adsorption and pseudocapacitors originating from surface Faradic redox reactions . In realizing the high capacity, the electrode materials play a crucial role in storing charges, thus enhancing the performance of supercapacitors . Recently, much effort has been focused on developing advanced electrode materials by either exploring new materials or performing surface modifications .…”

A main issue in the production of robust supercapacitors is the creation of efficient and cost‐effective electrodes. We present here the realization of a kind of nitrogen‐ and oxygen‐containing activated carbon microspheres made from divinylbenzene, diallyl phthalate, and acrylonitrile monomers, which can be produced on a large scale for use in supercapacitors. The supercapacitor's performance is optimized by adjusting the carbonization temperature of the microspheres. Our preliminary result shows that the supercapacitor displays a maximum capacitance of 300 F/g at the current density of 1.0 A/g and retains ~82% of the capacitance after 10,000 charge–discharge cycles.
