The ZnO/Ni2S3 composite has been designed and in situ synthesized on Ni foam substrate by two steps of electrodeposition. ZnO was achieved on Ni foam by a traditional potentiostatic deposition, followed by cyclic voltammetric (CV) electrodeposition, to generate Ni2S3, where the introduction of ZnO provides abundant active sites for the subsequent Ni2S3 electrodeposition. The amount of deposit during CV electrodeposition can be adjusted by setting the number of sweep segment and scan rate, and the electrochemical characteristics of the products can be readily optimized. The synergistic effect between the ZnO as backbones and the deposited Ni2S3 as the shell enhances the electrochemical properties of the sample significantly, including a highly specific capacitance of 2.19 F cm−2 at 2 mA cm−2, good coulombic efficiency of 98%, and long-term cyclic stability at 82.35% (4000 cycles).

“…There have been a few review articles summarizing the use of different characterization methods for the mechanism investigations in electrochemical SCs. [ 56–59 ] For example, Wang et al. discussed the use of in situ XRD, in situ XAS and EQCM for mechanism investigation of SC electrodes, mostly for metal oxides and hydroxides.…”

“…emphasized the use of in situ IR, X‐ray scattering, NMR and EQCM for SC mechanism investigation of electric double‐layer capacitor (EDLC) materials. [ 56 ] In our essay, we present and distinguish the characterization methods based on the categorized information to be derived, that is, crystal structure, structural, chemical, and electrochemical properties, for both carbon‐based materials and metal oxide/MXene/conducting polymers‐based pseudocapacitive materials. These methods also pave the way for constructing multifunctional SCs as highlighted in this essay.…”

Electrochemical supercapacitors (SC) with high power and long cycle life have been extensively studied and applied in certain areas. However, a majority of the efforts have been devoted to developing SCs with improved performance through novel electrode/electrolytes design. The full mechanistic understanding of SCs based on different electrode materials has not yet been realized. In addition, exploration of new functions for SCs to widen their applications must be accelerated. In this essay, the use of advanced characterization methods (in situ X‐ray diffraction, in situ X‐ray scattering, in situ atomic force microscopy, in situ nuclear magnetic resonance, in situ Raman/infrared spectroscopy, electrochemical quartz crystal microbalance, scanning electrochemical microscopy, etc.) to unveil the electrochemical process of SCs from different aspects will be discussed. The working principles, information to be extracted, and case studies of respective methods will be presented. The multipronged mechanism studies of electrode properties inspire and enable exploration of extra functions within the same electrochemical SCs. Realization of mechanically deformable, low‐temperature, color tunable, self‐healable, and self‐chargeable SCs; integrated SC‐sensors; and SC‐actuators with adoption of new electrode/electrolyte/current collectors/configurations are showcased. The remaining issues hindering the wide exploitation of SCs and the future development trend of SCs are also discussed.
