Abstract

Supercapattery a renowned energy storage device that comprises of the features of the battery and supercapacitor
at a time. This unique combination leads to the formation of such device that can deliver high energy density
with no compromise on the power density. Here, we have reported a unique class of material known as
metal organic frame works (MOF) for the application of energy storage devices. MOF comprises of exceptional
properties such as high surface area, excellent chemical stability and high porosity. The material was synthesized
via hydrothermal route in three steps. The structure, morphology, surface area, porosity and crystallinity
of the synthesized material were carried out through Tunneling Electron Microscopy, Scanning Electron
Microscopy, X-ray diffraction and Brunauer-Emmett-Teller. In order to investigate the energy storage application,
the electrochemical characterization was carried out in three-electrode assembly and the material express
excellent performance by showing a battery graded nature with specific capacity of 199.8 C/g. To further
investigate the application in energy storage field a supercapattery was formed as a real device by coupling
activated carbon as a cathode with MOF as an anode separated by porous membrane. This asymmetric assembly
expresses a specific capacity of 171.15 C/g and embraces an outstanding rate capability of 69% at 2.0 A/g.
Furthermore, this supercapattery delivers tremendous energy density of 38.05 Wh.kg−1 with an admirable
power density of 1600 W.kg−1. At last the supercapattery reliability was investigated through cyclic charge
discharge and the device has shown exceptional stability by sustaining its capacity of 100% even after 1000
consecutive charge discharge cycles.
