“…After years of research, a variety of electrode materials that can replace Pt have been found, such as nitrides, oxides, and sulfides. 17–19 Gnanasekar et al . successfully synthesized vanadium nitride nanoparticles using a template-free method and applied them in the CE of the DSSCs to obtain the PCE of 7.44%, which is higher than that of Pt CEs under the same conditions; 20 Kamesh et al prepared ZnCo 2 O 4 /N-doped rGO CE using the simple low-temperature hydrothermal method for dye-sensitized solar cell application, which exhibits improved surface area and gained the highest PCE of 5.84% ± 0.06%, via the introduction of N-doped rGO in the ZnCo 2 O 4 material to improve the DSSC performance of the CEs.…”

The development of the battery‐type electrode for the hybrid supercapacitor is very challenging owing to poor cycle stability. To overcome this problem, heterostructures would be an excellent alternative attributed to the synergetic effect of different materials physical properties, including electrical conductivity, mechanical flexibility, and so forth. Furthermore, heterostructures also offer significant redox reactions on account of more active sites, enhanced charge transfers kinetics via extra electron carriers, and ion diffusion rates, along with improved cyclic stability. Herein, we prepared heterostructures of Co3O4 nanospheres and WO3−x nanorods via a single‐step wet chemical method at a reaction time of 1 h (CoW1) and 6 h (CoW2). The electrochemical investigations reveal improved specific capacitance of CoW1 (157 F g−1) than CoW2 (188 F g−1) at 0.3 A g−1. Furthermore, an aqueous hybrid supercapacitor (AHS) shows the specific capacitance of 38 F g−1 at 1 A g−1. Notably, it exhibits a remarkable specific capacity retention of 93% up to 10 000 cycles at 100 mV s−1. Thus, CoW2 have great potential of electrode materials for the next‐generation energy storage devices.
