Title : Electrochemical analysis comparison of nitrogen undoped and doped Ti3C2Tx/Co3O4 hybrid composites on carbon cloth for application as electrode in supercapacitor


Supercapacitor provides great potential for good energy storage devices application, compared with other energy storage such as rechargeable batteries, fuel cell, dielectric capacitors and so on. Freestanding and flexible electrodes are vital for the development of flexible and wearable devices that store energy. But the significant trade-off between mechanical flexibility and electrode electrochemical performance limits the fabrication of efficient energy storage systems. In this research, we report the synthesis of a 2D material Ti3C2Tx and Co NPs on carbon cloth (CC) substrate. Co NPs was synthesized by microplasma reactors which eliminate harmful reducing agents and are efficient and cost-effective. And the Co NPs/Ti3C2Tx were synthesized by hydrothermal method for supercapacitor. These materials were characterized by scanning electron microscopy (SEM) Energy Dispersive Spectroscopy and X-Ray Diffraction for morphology and phases analysis. Besides these Transmission electron microscopies (TEM) and X-ray Photoelectron spectroscopy (XPS) were also done. For electrochemical analysis these materials were applied on the 2.25 cm2 carbon cloth as active material (working electrode) by various electrochemical techniques in 1 M H2SO4 electrolyte. The Co NPs/Ti3C2Tx electrode had a maximum gravimetric capacity of 52 mAh g-1 , specific capacitance of 580 mF cm-2 and 240 F g -1 at the current density of 1 mA cm-2 .


I have a multidisciplinary background. I have my BS in Metallurgy & Materials Sciences Engineering, MS in Mechanical Engineering and PhD in Mechatronics Engineering. I have been working on Printed Electronics since 2008. I have expertise in using several additive manufacturing techniques i.e. printing techniques like Electro-hydrodynamic Atomization technique (electrospray), Electrostatic Inkjet Printing technique (Drop-on-Demand & Patterning), Electro-spinning technique (Nano-fibers), Spin Coating, Dip Coating (thin films), Piezo-Inkjet technique, Screen Printing, Thermal Evaporation, Sputtering (thin films and patterns) and Casting (thin films) etc. In all the above mentioned techniques, patterns can be designed in the built in software and then can be fabricated by integrated commands to the machines. I have patented several processing & manufacturing techniques. I am interested to explore more materials (1D, 2D & 3D) and investigate their processing, large area production techniques and performance along with other functional layers for their applications in devices like Photovoltaic cells, Super-capacitor, Transistors etc., using additive manufacturing techniques I am deeply interested to explore more of the 2D materials like graphene, MXenes and play with their electronic properties by tuning their bandgaps by doping with nanoparticles/ one-dimensional materials or other 2D materials or by hybrid composites. My research interest includes exploring cheap and economical materials for energy harvesting and to develop processing techniques using optimized parameters to fabricate cheap product with excellent performance at larger area. I have strong will to continue my research on energy harvesting materials and their hybrid composites while using large area manufacturing processes. By doing so, the energy required for production can be minimized and maximum output can be achieved which is the major goal of current day research.
