Graphene based Electrode Materials for Energy Storage. Investigations on metal oxide electrode materials for Li-ion battery and Supercapacitor applications

      Аннотация: In response to the rapid global economic development leading to environmental pollution and enormous consumption of natural energy resources, there is an emerging demand for the growth of efficient and viable energy storage and conversion devices. Currently, Li-ion batteries and supercapacitors have materialized as prospective candidates to address this issue due to their excellent electrochemical properties. The electrochemical performance of the electrode materials is the most vital factor to determine the whole property of supercapacitors and LIBs. Transition metal oxides have been extensively studied as electrode materials for lithium ion batteries and supercapacitors due to their potentially higher specific capacities than that of commercial graphite. In the present investigation, various transition metal oxides such as Mn3O4, MnO, Fe3O4, LiFePO4 have been synthesized with the combination of graphene oxide and studies their structural, morphological and electrochemical behavior especially for Li-ion battery and supercapacitor applications.
