Abstract
This research focuses on the
preparation of sol-gel derived Sb-doped
SnO2 xerogel and aerogel with high surface
area. By mixing these powders with binder
and then coating on substrate, the
performance of the film electrode of a
supercapacitor in conjunction with KOH
electrolyte have been evaluated. Powders
heat-treated at temperatures below 400 o C
exhibited strongly distributed-capacity
phenomenon due to their small pores.
Powders heat-treated at temperatures above
600 o C have low capacity due to their small surface area. The optimum heat-treatment
temperature for maximum capacitance is ~
500 o C
