A study on the synthesis and characterization of CoMn2O4 electrode material for supercapacitor applications

PVP assisted morphology-controlled synthesis of hierarchical mesoporous ZnCo 2 O 4 nanoparticles for high-performance pseudocapacitor

“…Fig. 6b shows the calculated specific capacitance of the four materials at different scan rates (2,5,10,20,50 and 100 mV s -1 ) based on the CV curves using equation (1) and it clearly shows that P2 sample with the ring-like morphology has the highest specific capacitance results at all scan rates. Although the specific capacitance decreases gradually with the increase in scan rate, a high value of 459.26 F g -1 can still be maintained even at 100 mV s -1 for P2 sample.…”

“…Generally, SCs are divided into two categories based on the charge storage mechanism, namely: electrical double layer capacitors (EDLCs) and pseudocapacitors (PCs) [5]. EDLCs store energy using ion adsorption (no faradaic (redox) reaction), wherein the electrical energy is being stored in the electric double layer near the interfaces between electrode and electrolyte.…”

Investigating the Influence of Reflux Condensation Reaction Temperature on the Growth of FeCo2O4 Thin Film for Flexible Supercapacitor

“…The size and shape of complex spinel structure binary transition metal oxide material play a very important role in electrochemical performance because of their physical and chemical properties [21] . Spinel's like NiFe 2 O 4 , [22–23] CuCo 2 O 4 , [24–25] MgCo 2 O 4 , [26–27] ZnCo 2 O 4 , [28–29] NiCo 2 O 4 , [30–31] ZnMn 2 O 4 , [32–33] MnCo 2 O 4 , [34–35] and CoMn 2 O 4 [36–37] with different nanostructures are promising low cost and eco‐friendly alternative supercapacitor electrodes demonstrating excellent electrochemical performances. Binary metal oxides exhibit a synergistic effect with the contribution from the participating metal ions thereby improving the conductivity, capacitive performance, stability, and expanding potential window [38–40] .…”
