Conducting polymers and hybrid nano-materials for electrochemical storage; Polymeres conducteurs electroniques et nanomateriaux hybrides pour le stockage de l'energie

Abstract

In this work, we report first on the preparation of nano-structures based on poly-pyrrole and iron oxide nano-particles by oxidative polymerisation of pyrrole in colloidal solution of Fe{sub 2}O{sub 3}. The conductivity and the morphology of nano-composites were studied and related to the doping agent role and the weight ratio (Fe{sub 2}O{sub 3}/PPy). The specific capacity measurement on the composite electrode (based on the nano-composite, acetylene black and binders) indicate a significant enhancement of charge storage for nano-composites compared to pure poly-pyrrole. Then, we investigated the synthesis and characterisation of composite electrode based on poly 3-methyl-thiophene (PMeT), which depend on different methods of preparation, electrolyte and doping potential. Finally, a room temperature ionic liquid (RTIL) such as imidazolium tri-fluoro-methane-sulfonimide (EMITFSI), was used and seem to be a promising electrolyte since it increases further the capacity with a high stability during charge-discharge processes.
