“…Obviously, the drop in capacitance is likely due to the deterioration of the Bi(HHTP) electrodes. 49 The results show that the Bi(HHTP) 12 h electrode possesses a much better cycling stability of 72% after 1000 cycles, probably due to its good crystallization, which further results in longer nanobelts.…”

“…The CV curves of MoO 2 PNWs are similar in shape and have broad redox peaks at different sweep rates from 2 to 20 mV s À 1 (Figure 4a), suggesting a pseudocapacitive behavior. [56] The symmetric shape and proportional increasing of current density indicate its reversible Faradaic redox properties. As shown in Figure 4b, the MoO 2 PNWs exhibit a high specific capacitance of 1254 F g À 1 at the current density of 1 A g À 1 with an area mass loading of 1.27 mg cm À 2 , which is much higher than the reported work (Table S1).…”

Nanostructure construction is an efficient strategy to achieve high pseudocapacitive behavior with excellent charge storing ability and good cyclability. In this work, we constructed a novel pearl‐chains‐like MoO2 nanowires (MoO2 PNWs) on nickel foam via a facile solvothermal method. The formation mechanism can be inferred from the oriented growth and self‐assembly process under the contribution of benzyl alcohol and sodium dodecyl sulfate (SDS). The MoO2 PNWs deliver a high specific capacitance of 1254 F g−1 at 1 A g−1, outstanding rate performance with 73 % retention from 1 to 20 A g−1, and 91.5 % retention of capacitance after 2000 cycles at 10 A g−1. The outstanding performance is attributed to the continuous electron conductive path, short ion diffusion length and enlarged electrode‐electrolyte interface provided by the pearl chains like hierarchical nanowire, and good electrical conductivity owing to the free‐standing structures.

Flower‐like NiCo2S4@biomass‐graded porous carbon (NiCo2S4@BGPC) material was successfully prepared using a simple hydrothermal method and the pseudocapacitive performance was investigated. The results showed that the composite had good capacitive behavior and electrochemical activity due to the structural synergy of the porous carbon and flower‐like material. In this composite, the flower‐like NiCo2S4 had a large contact area with the electrolyte solution, providing many active sites for pseudocapacitive reactions. Meanwhile, the introduction of the porous carbon skeleton further ensured the structural stability of the composite‘s conductive network. In summary, the flower‐like NiCo2S4@BGPC material showed the high specific capacitance of 1322.5 F g−1 at the current density of 1 A g−1 and excellent coulombic efficiency (96.8 % after 1000 cycles at 10 A g−1). However, it has poor cycling stability (77 % of the initial specific capacitance after 1000 cycles at 10 A g−1), which can be attributed to blockage of the pore structure due to volume expansion during the redox process. In two‐electrode system tests, both NiCo2S4@BGPC//NiCo2S4@BGPC symmetrical supercapacitor and NiCo2S4@BGPC//AC asymmetrical supercapacitor showed good capacitance performance and cycling performance, implying potential applications of NiCo2S4@BGPC in commercial electrochemical energy storage.
