Organic Materials for Energy Storage

Development of electrochemically active organic materials for the electrochemical energy storage devices such as electrochemical capacitors and batteries is a major focus of research in NMG because they are low cost, naturally abundant and sustainable alternatives to their metal-based counterparts. Our research is focused on the identification of those organic systems which exhibit high redox capacitance, offer strong adhesion to the conductive substrates and show excellent cycle life.1 These organic systems also find applications for the grid-scale energy storage applications such as electrochemical flow capacitors.2,3 Recent highlights of our work can be seen on the cover pages of top sustainability journals, ChemSusChem and Energy and Environmental Science.4,5
