Impact of oxygen‐defects induced electrochemical properties of three‐dimensional flower‐like CoMoO 4 nanoarchitecture for supercapacitor applications

“…Remarkably, the solution resistance (Rs) of the rCMO electrode is estimated to be around 0.76 Ω, which is lesser than that of the rCMOA (0.87 Ω), CMO (0.99 Ω), and CMOA (1.18 Ω) electrodes, specifying the rich oxygen‐defect could effectively enhance the ionic conductivity of the rCMO electrode. These EIS results further elucidate that the ionic and electronic conductivity of the rCMO electrode are prominently influenced by the effect of abundant oxygen‐defect 41,62 …”

“…Markedly, the blue and red shift that occurs on the oxidation and reduction peaks are owing to the induced influence of the polarization of the electrode. 59,62 Figure 5C and Figure S7d depict the comparative GCD profiles of the rCMO, CMO, rCMOA, and CMOA electrodes at a constant current density of 1 A g À1 . As anticipated, the GCD time of the rCMO electrode is substantially longer than those of the CMO, rCMOA, and CMOA electrodes, representing a significant enhancement of electrochemical capacity owing to the rich oxygen-defects and texture properties.…”

“…These EIS results further elucidate that the ionic and electronic conductivity of the rCMO electrode are prominently influenced by the effect of abundant oxygendefect. 41,62 Based on the CVs at various scan rates, the charge storage mechanism of the rCMO electrode material can be determined according to the power-law relation 15,19 :.…”

“…Further, the excellent analogous patterns of these CVs elucidate the good reversibility of the electrodes. Markedly, the blue and red shift that occurs on the oxidation and reduction peaks are owing to the induced influence of the polarization of the electrode 59,62 …”
