AB  - Currently there is a need to develop new devices capable of storing energy which should be
lightweight, flexible and friendly to the environment. The aim of this research was to present the synthesis and
characterization of cassava starch conducting polymer and polypyrrole films which were used in the
development of an electrochemical accumulator. The starch films were chemically synthesized from native
cassava starch adding plasticizers and lithium perchlorate. Moreover, polypyrrole films were electrochemically
synthesized and doped with p-toluenesulfonic acid and indigo carmin. The characterization was carried out
using electrochemical techniques of cyclic voltammetry and electrochemical impedance spectroscopy. The
results indicate excellent electrochemical behavior of cassava starch films and polypyrrole films and good redox
activity which allow the accumulation of charge in the electrochemical accumulator device. This opens the
possibility of using these organic devices as an electrochemical charge accumulators.
