Research summary

My research interest focuses on design and development of ionic and mixed ion-electronic conductors which have potential application in the realm of electrochemical devices. Specifically, I am interested in developing ion conductors as electrolyte media which can replace volatile electrolytes in batteries, supercapacitors, fuel cells and actuators. Such replacement will enhance safety as well as cycle life of the concerned electrochemical devices. The detail investigation of charge transport mechanism through the ion conductors and at electrode-electrolyte interfaces via various spectroscopic and electrochemical methods are the pivotal aspects of my research field. The basic understanding of influence of the ion conduction property on the electrochemistry of electrochemical devices is one of the important part of the ongoing work.

The materials under investigation include soft materials such as ionic liquids, polymer electrolytes, ionic liquid confined polymeric systems and polymer nano composites. I am exploring various polymeric architectures of different functional specificity to form efficient ion percolative network through the soft mater electrolytes. Apart from soft materials I am also interested in developing solid state ion conductors, super ion conductors which can conduct ion efficiently as similar as liquid electrolytes for batteries and fuel cells. One of the major goal is to device all solid state devices with enhanced safety and improved charge transport across the interface. Optimum tuning of crystal structures and defect chemistry to design favourable pathways of ion conduction through solid state materials is the prime focus. Moreover, optimum hybridisation between soft polymeric and solid-state materials would be the attractive era of research I am working on. Such possibilities will not only propose new type of conductors but also open new opportunities to build hybrid devices.

My fascination to ionics, electrochemistry and my research expertise in material chemistry drive myself to establish the bridge between the material chemistry and electrochemistry via the pathways of ion and electron transport.
