Just to conclude Alan,please note ,polyanilline is a conjugated polymer,and to that end ;
New Supercapacitors Based on the Synergetic Redox
Effect between Electrode and Electrolyte
Redox electrolytes can provide significant enhancement of capacitance for supercapacitors.
However, more important promotion comes from the synergetic effect and matching between
the electrode and electrolyte. Herein, we report a novel electrochemical system consisted of
a polyanilline/carbon nanotube composite redox electrode and a hydroquinone (HQ) redox
electrolyte,
Keywords: supercapacitor; redox electrolyte; polyanilline; multi-wall carbon nanotube;
synergistic effect
Inspired by these works, in this paper, we prepared a redox composite electrode of polyaniline
and carbon nanotubes by in situ polymerization of aniline on the surface of the carbon nanotube, and
then we deeply investigated the synergetic redox interaction between polyaniline-carbon nanotube
and HQ in acidic aqueous electrolyte. By virtue of this extraordinary interaction, the electrochemical
properties of the supercapacitor were greatly improved. Notably, the specific capacitance is 1.58 times
of the highest value of redox electrolyte systems in past reports.
In a summary, the structure of PANI/F-MWCNTs composites is characterized by SEM, XRD,
and FTIR, The F-MWCNTs covered by the PANI build 3D conductive networks to increase the
synergetic redox effect in both the composite electrode and the HQ electrolyte of the SC. The
concentration of the HQ effect on performance of the SC is investigated, and the optimal
concentration of the HQ for the enhancement of performance is determined by a serious
electrochemical measurement. The highest specific capacitance from the GCD measurement is 7926
F/g at 0.2 A/g, a new record in the performance of SC. The maximum energy density reaches 114
Wh/kg in a two-electrode symmetric electrochemical system at 1 A/g in 2 M HQ-1 M H2SO4 solution.
In addition, the specific capacitance retention is 96% after 1000 galvanostatic charge/discharge cycles,
indicating an excellent cyclic stability.

I wonder if Mainak, is working from the other way around Alan?, in any event , I have the upmost faith in Mainak and his team to come up with a SuperCapacitor to meet the markets needs, offering both capacitance and density .
