Abstract

Perovskite oxynitride materials find wide applications in energy storage and conversion. In this work, we have developed copper doped Barium tantalum oxynitride (BaTaO₂N) for electrochemical energy storage in supercapacitors. The material was synthesized using a green and facile “soft urea synthesis” method. Further, its crystal structure, morphology and dopant atom composition were characterized. Defect energetics calculations were performed to examine the lattice stability and nitrogen fixation in copper doped BaTaO₂N. The symmetric supercapacitive behaviour of the material was studied in detail. The material delivered a specific capacitance of 944 F/g at 1 A/g. The device delivers a maximum energy density of 24Wh/kg and a maximum power density of 9.8 kW/kg. The leakage current for the symmetric device was 0.65 mA. Overall, the present work reports the development of a novel transition metal doped perovskite oxynitride for supercapacitor applications.

期刊介绍： Launched in January 1998, Inorganic Chemistry Communications is an international journal dedicated to the rapid publication of short communications in the major areas of inorganic, organometallic and supramolecular chemistry. Topics include synthetic and reaction chemistry, kinetics and mechanisms of reactions, bioinorganic chemistry, photochemistry and the use of metal and organometallic compounds in stoichiometric and catalytic synthesis or organic compounds.
