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.

Well, 1.5 A/g is specific current not current density.

For the areal capacitance use only the area (S cm2) of the electrode, discharge current (I in A) and discharge time (t in s):

Ca=It/(SV) V=0.5 V you will get Ca in F/cm2

Mohit Saraf

Thanks Prof. Grgur

Jude Iroh

S/cm2?

Dear Dr. Iroh,

S or A is a surface area in cm2

Greetings

Branimir

Yes, but conductivity units is in siemen per centimeter square (S/cm2). It was given as Scm2 in the previous write-up. That was what I was trying to point out.
