Performance optimization of bimetallic Co3(PO4)2@Ni3(PO4)2 electrodes for supercapacitive applications

The recent high rises in energy crisis worldwide have prompted scientists and scholars to incessantly research on modern energy conversion and storage devices. In this work, we employed the service of composites of transition bimetallic phosphates in fabrication of electrodes for usages in supercapacitors. The morphology of these electrodes showcase a mixture of leaf, sphere and platelet nanoparticles spread evenly on the surface of the substrate with respect to precursor ratio variations. These fabricated electrodes indicated appreciable crystalline nature from XRD results. Various band gap energies of these electrodes are very low, supporting their excellent electrochemical performance. The excellent charge storage performance of various electrodes were evident from the electrochemical studies and indicate that Co 3 (PO 4 ) 2 @Ni 3 (PO 4 ) 2 electrodes are potential electrodes for supercapacitors applications. Various electrochemical results clearly designated that bimetallic Co 3 (PO 4 ) 2 @Ni 3 (PO 4 ) 2 composites formation improved electrodes supercapacitive performance and cycle stability.
