dc.description.abstract | In this paper we present results obtained for energy storage units developed using polyaniline and
polythiophene modified electrodes. The voltage potential prof
iles for recharge/discharge are either linear or
exponential. Nucleation over
-
potential has been observed in some profiles where there is a phase transition.
It is
observed that hydrocarbon gel: bentonite electrolyte mixtures yielded relatively high initia
l voltages and that,
this voltage also depended on the hydrocarbon: bentonite ratio. The potential decay profile for potential at Vo,
3/4Vo, 1/2Vo and 1/3Vo yielded linear and exponential curves for various hydrocarbon:bentonite mixtures.
The capacity (C)
were 0.0014 Ah, for the 2:1 energy unit and 0.00035 Ah for the 3:1 energy unit.
The electric storage density (ESD) for the 2:1 and 3:1 energy units were 4.7 × 10
