A synopsis of some of my ongoing research is given below. A rapid increase in human population and global economic development create a strong demand for energy, while the fossil fuel reserves that we rely heavily on are depleting. In addition, consumption of fossil fuels also causes consequential environmental pollution. The introduced Lithium-ion batteries, even with recent modifications, do not have the desired efficiency in 3

4 applications; specifically the full charge/discharge time takes up to an hour, which is too long for electronic systems. This problem can be overcome by supercapacitors, based on graphite materials and their composites. These storage devices with high capacitance properties were proposed just recently and have attracted great attention from scientists as an alternative storage media. Especially graphene, which has been the focus of many recent studies as well, is in particular suited for such devices due to its high surface-to-volume ratio. It was shown, that sandwich graphene structures as supercapacitor contacts helps to increase the capacitance value of devices, but the production of such well-defined sandwich structures is still a challenging goal. Similarly, metal oxides and sulphides are known to act as supercapacitor electrodes due to their pseuodocapacitive properties. Aim of our ongoing research is to fabricate novel 2D materials and their graphene hybrids for supercapacitors and flexible devices for alternate renewable energy storage devices. Preparation of novel 2D materials and nanocarbon (graphene) based hybrids by CVD and other techniques. Characterization of the materials by surface sensitive analytical techniques (X-ray photoelectron spectroscopy (XPS), Infra-red spectroscopy (IR) etc. and comparison of material properties to the results of atomistic computer simulations. Development of free standing, flexible supercapacitor electrodes with high energy density, power density and specific capacitance. Fabrication of high energy density asymmetric coin cell supercapacitors based on metal sulfides and graphene as cathode and anode materials respectively. Development of working prototypes, short- and long-term supercapacitors. Electron field emission (FE) of nanomaterials has gained considerable interest in recent years since they have potential applications in flat-panel displays, vacuum microelectronics, etc. Our research is focused to develop high-field enhancement 2D materials with low threshold fields at low cost and suitable for industrial-scale production.

I have fabricated Li-ion batteries and supercapacitors based on such 2D materials and their graphene based hybrids and their energy storage properties have been demonstrated. Research work at Purdue University, USA ( ) I have worked on preparation of single and few-layered graphene and CNTs by plasma enhanced chemical vapor deposition and their applications in electronic, optical and thermoelectric devices. Also, some of my works are on surface enhanced Raman studies of graphene and thermal interface properties of Boron nitride composites. I have studied surface-enhanced Raman scattering properties of Au and Ag nanoparticles decorated few- 5

6 layer graphene substrates, which could detect very low concentration of rhodamine 6G, BSA, thiols and amines. Research work at National University of Singapore ( ) I have pursued research on fabrication of single nanowire based field effect transistors by electron beam lithography during my postdoctoral work at National University of Singapore. I have studied room-temperature ferromagnetic properties, field emission and energy storing properties as well as optical limiting properties of Vanadium oxides nanobelts, nanowires and nanoflowers. The nanostructures are found to exhibit large optical nonlinearity, leading to optical limiting behavior and the nonlinearity is probed using Z-scan technique. Also, we have fabricated field emitting devices based on W18O49 nanowires. Present Research Students at IIT Bhubaneswar: Mr. Satyajit Rath Mr. Kusha Kumar Naik Mr. Surjit Sahoo Dr. P. Karthick Kannan (Post doc) Future research plans: The ever-growing energy demand has greatly stimulated research on exploring highperformance electrode materials for energy-storage devices. Supercapacitors, also known as electrochemical capacitors, have been considered as one of the most promising energy-storage devices because of their many advantages as compared to the conventional capacitors, including high power density and longer lifespan. Supercapacitors hold great potential as power sources for applications requiring fast bursts of energy or as back-up power sources in electric vehicles. However, the performances of the conventional supercapacitors based on rigid electrodes are limited due to the lack of the desired electrode porosity and low capacity. Moreover, optimum electron as well as proton conductivities are also necessary to achieve high performance. These factors in turn depend on the physical nature of the electrode material, for instance nanoparticles 6

7 are known to possess higher capacitance and can form flexible electrode structure as compared to its crystalline form. Therefore, it is extremely important to tune the structure of the electrode material. Flexible materials for energy storage devices have recently received great interest in many emerging wearable or rolling-up modern gadgets, such as electronic papers, collapsible displays and other personal multimedia devices. Hence, these applications require highly efficient electrode materials with good electrochemical properties, high mechanical integrity upon bending or folding and lightweight property. In particular, the capacitance of a supercapacitor is determined by the surface area of the electrode, which is accessible for the electrolyte. Due to the upcoming demand for high power and high energy for several applications (stationary, load levelling, hybrid concepts, etc.) supercapacitors with 1D and 2D carbon materials, such as carbon nanotubes (CNTs), carbon nanofibers (CNF), graphene, reduced graphene oxides (RGO) and their composites with nanostructured binary metal oxides and sulphides have recently attracted attention. The above class of composite electrode shows excellent electrochemical performances and they can be tailored to form flexible and freestanding electrodes. In our approach, I propose to explore the possibility to use combination of graphene and binary transition metal sulfides with high surface area, highly conducting and electroactive nature, which may lead to the design of novel flexible and free standing electrodes for high performance supercapacitors. Typically, the as-synthesized graphene and metal oxide or sulfides sheets are randomly oriented with respect to the current collectors in a supercapacitor in the conventional stacked geometry prepared by various chemical routes. In such cases, the electrolyte ions are often limited from penetrating far inside the planes of the 2D structures. Another problem is the agglomeration of graphene sheets. These effects lower the complete utilization of the electrochemical surface area of graphene or other layered structures and consequently limit the extent of the electric double layer supercapacitor formed at the interface. Hence, if in-plane or vertically aligned electrodes of 2D materials can be made, it could offer new opportunities for the electrolyte ions to enhance interaction with all the layers, which could lead to a full utilization of the high surface area offered by the layered structures. The focus of my proposal is to develop high performance as well as flexible and freestanding electrodes based on 2D carbon materials (graphene) and their hybrids with 7

8 nanostructured binary metal sulfides (MCo 2S 4 (M=Ni, Zn, Mn, Fe)) prepared by chemical vapour deposition (CVD) on Cu and Ni foils. By using this novel electrode system, durable energy storage devices with high energy density, power density and working voltage can be realized. Further, the composites will be modified with conducting polymers such as polyaniline and polypyrrole to enhance the performance. The prepared materials will be well characterized by XRD, FIB/SEM, TEM, EDAX, XPS, FTIR, Raman, AFM and BET. Further, it is also important to understand the electrochemical processes taking place on these electrode materials, especially get insight into the synergetic effect of various functional groups on carbon in these novel electrode materials. This can be achieved by developing in situ characterization techniques. Finally their physical, chemical properties and growth mechanism will be studied, and mechanisms for the enhanced performances will be proposed and explained by theoretical multiscale simulations. In particular, the mechanical properties and geometry of flexible carbon-based electrodes will be assessed using the analytical potential and continuum-theory models (with the parameters derived from atomistic simulations), and the information on the atomic structure obtained from the experiments. The atomic structure of the interface between graphene and nanostructured metal oxides will be studied using advanced density functional theory (DFT) methods which include van der Waals-type interactions. The amount of stored charge, energy and the electric potential difference will be assessed. The calculated values will be compared to the experimental data as the theoretical limit, and suggestions for the optimum materials/composites will be made. The iterative interactions between the simulation and experimental groups should make the research efficient and allow the consortium to achieve the main goals of the proposal. Also, we aim to achieve high energy density of supercapacitors based on binary metal sulfides (MCo 2S 4 (M=Ni, Zn, Mn, Fe)) and graphene in an asymmetric coin cell configuration. Generally, advanced supercapacitors should possess high energy density without sacrificing power delivery and cycle life. It can be seen from the calculation equation of energy density, E (CV 2 ) / 2, that E (energy density) is proportional to C (specific capacitance) and ΔV (potential window of discharge). Thus, it will be an effective method for improving the energy density that increasing the specific capacitance of material or enlarging the working voltage window. It is well known that specific capacitance is often limited by the material properties. So, expanding voltage window becomes the most effective way for enhancing energy density. For 8

9 aqueous electrolyte, cell voltage or the supercapacitor voltage window is usually about V. But the voltage window of organic electrolyte can even achieve to as wide as V. Thus, the most commonly used method of expanding voltage window is to choose organic electrolyte or ionic liquids. However, organic electrolyte or ionic liquid can give rise to other problems, e.g.: safety, toxicity, flammability, high-cost, etc. As a result, assembling asymmetric full-cell supercapacitors becomes another prefer method to improve voltage window. It takes advantage of the potential windows of two different electrodes to expand the device operating voltage. Even in aqueous electrolyte, the voltage window can also be obviously extended and the energy density might be significantly improved. In our approach we will be using graphene on metal foils (Cu, Ni) and binary metal sulfides (MCo2S4 (M=Ni, Zn, Mn, Fe)) on metal foils (Cu, Ni) grown by CVD as electrodes to fabricate coin-cells of supercapacitors.
