The novel material CuZnCdO metal nanoparticles have been synthesized with different concentrations through green synthesis using fresh A. heterophyllus leaf extract as a reducing agent and graphene oxide derived from A. heterophyllus dead leaves. XRD, FESEM, EDAX, FTIR and FT-RAMAN analysis confirms the structural properties of rGO/CuZnCdO nanoparticles. BET has been used to investigate the surface area of the nanoparticles. It is a very challenging material that shows the highest specific capacitance of 882.5 F/g with non-hazardous and eco-friendly. Without any decay, the charge carrier concentration has performed up to 5000 cycles which indicates the material has good stability. The energy density and power density has been calculated by Ragone plot. This illustrates that the material has high capacitive behavior.

A new electrochemical energy storage device, comprising a faradaic rechargeable pseudo-capacitor type electrode with a non-faradaic rechargeable capacitor electrode, is successfully developed for potential applications in smart electric grids. Mapping new electrodes possessing both high energy and power densities as well as long cycle life is vital for the sustainable energy management. In this work, we present a new approach to design electrodes, fabricated from sustainable resources by hybridizing calcined eggshell capacitor anode with a mixed binary metal oxide pseudo-capacitor cathode. Calcium carbonate (calcite), obtained from the biowastederived eggshell, is an effective electrode material and operates via accumulation of ions on the electrode surface, providing a high discharge capacitance of 100 F/g through a non-faradaic process. The calcite present in eggshells is found to be a valuable renewable resource which can be utilized for energy storage through suitable process design. Otherwise, such potentially useful materials (eggshells) are generally discarded as landfill. The mixed binary metallic oxide (NiO/Co 3 O 4 ) showed a typical pseudocapacitive behaviour associated with both charge transfer reactions and electrostatic means provided a high discharge capacitance of 225 F/g. The fabricated prototype hybrid device provides an energy density 35 Wh/Kg at a power density 420 W/Kg. The charge storage characteristics of the hybrid device depend heavily on the current rate employed. The design and fabrication of new sustainable electrode materials provides an understanding of materials and their electrochemical performance in the high-voltage window.[a] Dr.

“…Moreover, with the increasing demand for portable and wearable devices, flexibility and foldable feature of electrode are highly needed. For some flexible materials such as carbon fibers/fabrics, metal mesh and polymer sponge, the low specific surface area and poor conductivity greatly limit their wide application in electrochemistry [14][15][16][17][18]. One promising way to solve the above-mentioned problems is to coat/mix these supports with a conductive and porous layer while keeping their original shape and flexibility [19][20][21].…”
