How specific capacitance depends on mass loading?

09 September 2016 1 3K Report

It is okay that more mass loading may increase resistance and therefore capacitance will be less. However, what should happen ideally when we increase mass loading?

If I use very less mass loading, will it give better results?

Ioannis Samaras

Dear Mohit Saraf,

what if you do the experiment and show us, please, the graph capacitance vs. "mass loading or thickness".

Is it necessary that a composite of metal oxide and rGO should always exhibit better energy storage properties compared to only metal oxide and rGO?

Kindly shed some light on it. In my case, the rGO alone is providing better supercapacitor properties than composite.
