I want to decide the optimizing range for the synthesis of my thin films (transition metal oxides and transition metal sulphides) to be used as electrode material in supercapacitors so as to get the best electrochemical performance.
The coulombic efficiency of my supercapacitor device is increasing with the increase in the applied current density of charging-dicharging. Can someone please enlighten me on this trend because...
