Facile synthesis of nanostructured CuCo2O4 as a novel electrode material for high-rate supercapacitors

Abstract

CuCo2O4 nanostructures were synthesized through a facile solution combustion method. Electrochemical investigations demonstrate a novel electrode material for supercapacitors with remarkable performance including high-rate capability, high-power density (22.11 kW kg(-1)) and desirable cycling stability at different current densities.

Hydrogen ion conducting starch-chitosan blend based electrolyte for application in electrochemical devices

“…This phenomenon is resulted from the effect of internal resistance. Internal resistance is reported to increase with increasing charge-discharge cycle [68][69][70]. At higher resistance, less charges flow causes less current flow which result a decrease in C s value as shown in Table 7.…”

Facile synthesis of maguey-like CuCo2O4 nanowires with high areal capacitance for supercapacitors

“…This advanced configuration for maguey-like CuCo 2 O 4 nanowires electrode schematically illustrated in Fig. 6b, which distinguishes from the capacitance increasing of those normal nanostructure in previous reports [17,25,26,29], where only the nanowires provided single channel for charge transition. Based on these observations, maguey-like CuCo 2 O 4 nanowires electrode has the following characteristics beneficial to capacitance improvement.…”

Characterization of MgCo2O4 as an electrode for high performance supercapacitors

“…The redox peaks in CV of Fig. 4(a & c) are attributed to faradic reaction involving Co 4+ /Co 3+ and M 2+ /M + with OH À ions [30]. The redox peak of the electrode materials can be attributed to the following reactions [3,[31][32][33].…”
