Abstract
The versatile importance of hybrid supercapacitors in energy storage applications craves the outstanding electrochemical behavior of electrode material. In this study, we have grown several electrodes of cobalt-copper-manganese sulfide (CCMS) with different concentration of cobalt and copper on a current collector (Ni foam) by espousing one-step co-electrodeposition approach. The morphological aspects of contrived electrodes have been characterized by FESEM.. Electrochemical characterization reveals the substantial performance of S2 electrode (Co25Cu75MnS) as compared to other compositions. After the experimental investigation, the dependence of inherent charge storage mechanism of CCMS on the concentration of Co and Cu have been scrutinized thru stimulating theoretical approaches. Different mathematical models employed to ascertain the dominant charge storage mechanism involved during electrochemical charge storage and scrutinizing their redox reaction stability. The finding illumines the enhanced electrochemical performances of electrodes with prevalent battery-type charge storing phenomenon which support for the construction of advance hybrid energy storage devices.
