| dc.description.abstract | Spinel copper manganese oxide nanoparticles combined with acid-treated multi-walled
carbon nanotubes (CuMn2O4/MWCNTs) were used in the development of electrodes for pseudocapacitor
applications. The CuMn2O4/MWCNTs preparation involved initial synthesis of Mn3O4 and
CuMn2O4 precursors followed by an energy efficient reflux growthmethod for the CuMn2O4/MWCNTs.
The CuMn2O4/MWCNTs in a three-electrode cell assembly and in 3 M LiOH aqueous electrolyte
exhibited a specific capacitance of 1652.91 F g1 at 0.5 A g1 current load. Similar investigation in
3 M KOH aqueous electrolyte delivered a specific capacitance of 653.41 F g1 at 0.5 A g1 current
load. Stability studies showed that after 6000 cycles, the CuMn2O4/MWCNTs electrode exhibited a
higher capacitance retention (88%) in LiOH than in KOH (64%). | en_US |
