Organic Electrode Materials For Electrical Energy Storage Devices

Abstract

In order to develop next generation cathode materials for electrical energy storage (EES) devices, this study has focused on synthesis and electrochemical characterization of redox-active organic materials. Organic molecules are composed of widely-available, lightweight elements, and its properties can be rationally tuned using well-known principles of organic chemistry. Moreover, both amorphous and crystalline organic materials can accommodate more dramatic changes in volume than the inorganic systems currently being proposed for next-generation lithium batteries. Discrete organic compounds are inadequate on its own: the high solubility in electrolyte media results to a rapid fade in the capacity and organic materials are usually insulators. In order for these materials to be of practical use, it was crucial to develop methodologies and new materials by which these species can be confined to an insoluble conductive substrate without altering their electrochemical properties.
