Molecular simulations of lithium insertion/deinsertion processes in novel lithium ion battery anode materials

Metal oxides, e.g., SiOx and SnOx, and Si are regarded a prime candidate materials for high energy batteries. However, many challenges need to be addressed, including issues related to the large volume variation during the discharging/charging process, poor electrical conductivity, and  unstable solid electrolyte interphase films, which restrict its stable cycle life as well as commercial viability. Here, we will use theory to first understand the Li insertion/deinsertion process and then design silicon and SnOx nanostructures that attempts to resolve such challenges.

Mechanisms of failure in lithium ion battery

Lithium ion batteries are used with a number of electronics gadgets.
Extending their application to high power applications is a major
research problem due to the rapid loss in capacity in these batteries. The goal is to investigate mechanisms that lead to the detoriation in
battery performance primarily using computer simulations and comparing
with experimental results obtained in our group.

Students are encouraged to approach Prof. Chatterjee for more information.

Process Intensification through multifunctional reactors and catalysis

The work involves identification of a gowing fine chemical and develop a process for the same. Catalyst would be identified and synthsized if required. Catalyst would be characterised and teh performance will be evaluaed and comapred with the conventional counterpart. Various strategies such as combining reaction and separation in a single unit would be explored. Kinetic modeling would be performed for the new catalyst. Modeling and simulation would be performed to comapre the same with the conventional process and bring out the added benefits offered by the porposed process.  read more »

Multi-purpose distillation unit

Multi-component Distillation unit.jpg

Distillation is the most widely used separation technique in the chemical and petroleum industry and is performed in either tray or packed columns. The set-up can be used for separation of azeotropic mixture using distillation methods such as Extractive distillation, Heterogeneous azeotropic distillation, Distillation using ionic salts, Pressure-swing distillation and Reactive distillation.  read more »

Micro Annular Gear Pump

gear pump.jpg

These micro annular pumps can maintain flow rates from 0.0015 to 1152 ml/min at differential pressures up to 150 Bar with attributes like low shear stress and reverse pumping. All types of liquids having viscosities between 0.3 and 1000,000 mPas can be passed through these pumps. It has an integrated 16-bit microcontroller for speed and position control for continuous and discrete dispensing tasks. Operating temperature ranges from -5 to 60 °C.  read more »

Mini Extruder(Avanti Polar Lipids Inc. )

thin film extruder.jpg

The Avanti Mini-Extruder allows the preparation of small unilamellar vesicles from different lipid species by extrusion. The heating block allows the extrusion of unilamellar vesicles at elevated temperatures, which is critical for the successful production of vesicles from phospholipids with a phase transition temperature (Tm) above room temperature.
