- Abstract
Cobalt pyrophosphate (CoPO) nano/microstructures (oblong plate, microplate, microflower, and hierarchical architectures) have been successfully synthesized through calcination of NHCoPO·HO nano/microstructures. More importantly, supercapacitive performances of CoPO nano/microstructures were studied using cyclic voltammetry, galvanostatic charge/discharge measurements, and electrochemical impedance spectroscopy methods in 3.0 M KOH solution. These results show that CoPO hierarchical architecture electrodes exhibit high specific capacitance of 367 F g at current density of 0.625 A g in aqueous KOH solution. CoPO hierarchical architecture electrodes remain 96.2 % of the initial specific capacitance after 3,000 charge/discharge cycles.
