if you are using same current density (mA/g) for both anode cell, then the cell with less discharge time (h) will have less specific capacity (h* mA/g= mAh/g).

Dear Ganesh,

you need to define the term "better". Or avoid it in general. I diagree with the formular presented by Dhrubajyoti Bhattacharjya because the current density is the current per area [mA/cm²]. Therefore a shorter time means a shorter areal capacity [mAh/cm²]. If your statement Ganesh Sainadh Gudavalli is correct, that the gravimetric capacity is constant, you have just used different masses of active material.

You could say, that you have a "high power - low capacity" electrode vs a "high power - high capacity" electrode.

Now you can determine what your purpose for the electrode is and then decide, which one fits the needs.

I would assume that you have a thick and a thin electrode. Different Porosity could also be an option, but this should result in differend current density - gravimetrical capacity dependencies between the two samples.

Hope this helps,

Sascha

Dear Ganesh Sainadh Gudavalli ,

I completely agree with Sascha Wolter . In your case, if your two electrodes have same mass loading then you can compare directly (if they are same active material), otherwise you should compare them based on their specific weight i.e. specific gravimeteric capacity.

i believe that your mass loading must be different, that's why it took different time to charge/discharge for same capacity. In short, I think the C-rates are different for each electrode.
