Abstract
The avant-garde supercapatteries have received substantial curiosity for their noteworthy electrochemical performance. Devising battery-type substances with appreciable electrocapacitive accomplishment and high electrical transmittance is imperative to boost the energy stowing knack of supercapattery devices. A pure CoWO
4
nanostructure and a composite of CoWO
4
incorporating r-GO were prepared by hydrothermal method. The XRD and FTIR results validated the effective development of high-quality CoWO
4
and r-GO. FESEM images reveal a nanosphere-like architecture of CoWO
4
over r-GO sheets. The pure and composite nanomaterials show good battery-like traits in electrochemical studies. The CoWO
4
/r-GO electrode exhibits better electrochemical activity compared to pure sample. The specific capacitance (and specific charge capacity) calculated at a current density of 2 A g
−1
for CWO/r-GO and CWO is 382.7 A g
−1
(158.1 C g
−1
) and 262.7 A g
−1
(105.1 C g
−1
), respectively. The results obtained herein evince that the developed nanocomposite is a propitious electrode candidate for supercapattery.
