Nanocomposites based on graphene derivatives, two-dimensional metal oxides and conjugated polymers for application in flexible energy storage devices

Abstract

Faced with the current energy crisis and environmental problems, the need to exploit new materials as sources of clean and renewable energy as well as the development of new miniaturized energy storage devices with high efficiency and stability are urgently required. The synthesis of new nanocomposites, based on the synergistic effect of different materials, has great importance in the contribution to the development of research lines in energy. The objective of this project is to obtain new materials for use in energy storage devices, whose active layer (material that will present electrochemical capacitance and electrical conductivity) based on novel ternary nanocomposites, made from the mixture of reduced graphene oxide, oxides of mixed transition metals in two-dimensional form and a conductive polymer. New routes of synthesis of the nanomaterials, variations of the materials used and the proportions of the materials present in the active layer will be tested in order to produce the best possible flexible energy storage device.
