Please explain VersaSTAT MC Multi channel electrochemical system with details regard handling of software for a VersaSTAT Studio, please how/where to set potential window value and Where to set the Current Density value (1A, 2A, 3A or mA) into Charge-Discharge in order to supercapacitor form a charge discharge experiment.
Using VersaSTAT chronopotentiometry, what is the procedure of cyclic charge discharge method procedure step wise, 1) where to set applied potential and current density value (A or mA). CV and Impedance much better.
Please anybody help me how to what is the procedure using in (VersaSTAT Studio) software chronopotentiometry charge discharge options and settings.
please mention references for the same.
In Gammry 3000, you can use cyclic charge discharge at different current densities to sequence of cycles. For chronopotentiometry, you use a constant voltage and different current values. I think the same for VersaSTAT.
Thank you Mohamed Elsayed Harb, sir can you explain the procedure Chronopotentiometry, yes sir general point of view constant potential window (-0.54 to 0.64 V) and different current densities 1 A/g, 2 A/g, 3 A/g, 4 A/g, 5 A/g.
Use Galvanostatic Charge-Discharge method (it is a Chronopotentiometric method: a constant current is maintained, the applied potential vs time is recorded). You have to calculate the constant current as "desired current density x electrode mass"). You don't have to set an applied potential (the potentiostat will do the work for you). But you may set a limit for the highest applied potential or the maximum charge.
