1. Lithium-ion Battery Recycling

Objective:To recycle lithium-ion battery materials such as cobalt from the battery for reuse in producing new batteries.

With the ever-increasing demand for energy being fulfilled by rechargeable lithium-ion batteries (LIBs), the accelerated production of these devices will soon translate into massive amounts of waste. The development of LIB-specific recycling methods can minimize the impact of this waste and also alleviate constraints on the supply chain of battery manufacturers. We are trying to develop highly efficient concept to extract value from LIB waste using a deep eutectic solvent (DES).

2. Extractive Desulphurization of Gas Oil Using Deep Eutectic Solvents

Gas oil is mostly used as transportation fuel. Sulfur compounds present in gas oil upon combustion releases SOx and sulfate particulate matter which cause serious environmental pollution. Therefore, regulatory bodies are imposing stringent regulations across the globe with regard to the maximum level of sulfur in transportation fuels. Euro- VI regulations require less than 10 ppm of sulfur in gas oil. The target to achieve lower level of sulfur content in gas oil is going to be very challenging in near future due to the necessity of processing high sulfur content crude oil to compensate the deceasing availability of low sulfur content crude oil.
In refineries, hydrodesulfurization (HDS) is used for the removal of sulfur compounds present in gas oil. Typically, the HDS process operates under severe conditions, high pressure and temperature, and involves catalytic treatment with hydrogen to convert the various sulfur compounds to H2S. But this process has a limited capacity to efficiently remove the heterocyclic sulfur compounds such as dibenzothiophene (DBT) and 4, 6-dimethyldibenzothiophene (4, 6-DMDBT). Therefore, to meet low sulfur-level by the HDS process, severe operating conditions and high economic investments are necessary. Therefore, research work is going on across the globe for the development of non-HDS technologies for gas oil processing such as oxidative desulfurization, selective adsorptive desulfurization (ADS), bio-desulfurization and solvent extraction desulfurization (SEDS).
Extractive desulfurization is one of the most promising desulfurization method because it operates under mild conditions and has simple separation mechanism. Conventional organic compounds such as sulfolane, N-methyl-2-pyrrolidone and dimethylformamide have been studied as solvents in the extraction process in the last few decades. But, the commonly used solvents are volatile, flammable, toxic and they have serious consequences for the environment. Hence, research efforts are focused on finding the suitable solvent for use in deep desulfurization process which has less impact on the environment. In last decade, deep eutectic solvents (DESs) have emerged as alternatives to conventional solvents. A DES is a mixture of two or more components that has a melting point less than that of any of its individual constituent. DESs have many advantages such as very low vapor pressure and non-flammable, can be easily synthesized with high purity and are generally cheaper due to the simple synthesis process. By carefully choosing the components of the DES, it is possible to obtain non-toxic and biodegradable solvents.
Therefore, the present work is focused on the development of a separation technology for the selective extraction of sulfur compounds from model gas oil using novel deep eutectic solvents.

3. Deep Eutectic Solvents as Electrolytes for Nanomaterials-based high-performance Supercapacitors

In last decade, Supercapacitors (SCs) have attracted considerable interest in academia as well as in industry. This has primarily been the result of three attractive characteristics of supercapacitors: high power density (>10 kW/kg), rapid charging/discharging (milliseconds to seconds) and long-life cycles (> 10000 cycles). Due to these, these devices can replace batteries when high power delivery or long cycling stability is required, or there is a need for intermittent energy with variable power demands. Despite their promising features, the widespread use of supercapacitors is still limited due to their low energy density. The energy density of supercapacitors (~5 Wh/kg) is significantly lower than that of widely used Li-ion batteries (~150 Wh/kg).
To overcome this challenge, extensive work has been devoted to increase the energy density of supercapacitors. Since the energy density (E) of SCs is proportional to the capacitance (C) and the square of the voltage (V), increasing either or both of the capacitance and the cell voltage is an effective way to increase the energy density. This can be achieved through the development of electrode materials with high capacitance and electrolytes with wide potential windows. The operating cell voltage of the SCs is largely dependent on the electrochemical stable potential window (ESPW) of the electrolytes. Aqueous electrolyte-based SCs are non-flammable, inexpensive, have higher ion conductivity and give often rise to higher capacitance due to smaller ions. But usually have an operating potential window of 1.0-1.3 V. Commercial supercapacitors commonly use organic electrolytes. The main advantage of organic electrolytes is their wide electrochemical stability window (~ 2.7 V). However, the use of volatile, flammable, toxic and expensive solvents in electrolytes poses several safety problems upon long term application of the electrochemical devices. In order to minimize the use of volatile solvents in the preparation of electrolytes, the concept of non-volatile solvent based electrolytes has been proposed by various researchers.
During last decade, intensive investigations have been carried out on using ionic liquids (ILs) as promising electrolytes for SCs due to their interesting properties such as low volatility, high thermal and chemical stability, high flame retardancy, high electrochemical stability, wide electrochemical windows, and high ionic conductivity. ILs based SCs generally have potential windows of 3.5-4.0 V which makes ILs very suitable electrolytes for energy storage devices. However, high-cost of ILs are of great concern. Thus, it is very important to find much cheaper, greener and safer electrolytes for supercapacitors.
Recently, deep eutectic solvents (DESs) have emerged as alternatives to ILs. This is because of the properties of DESs resemblance to ILs e.g. wide liquid range, low vapour pressure and non-flammability. The preparation of DESs involves the mixing of low-cost and environmentally friendly starting materials. This results in comparatively low production cost with respect to conventional ILs and permits large scale applications. Also, the bio-compatible, bio-degradable and non-toxic nature of DESs encourage the usage of DESs in various applications.
This work will study the feasibility of deep eutectic solvents as a novel class of electrolytes for supercapacitors.
