Assistant Professor Grade-I
Energy Science and Engineering
The world is striving for clean and efficient forms of energy due to various factors like – increase in global energy demand, limited fossil-fuel resources and global warming. The commercialization has evolved through portable batteries for laptops, mobile phones, working tools to hybrid electric vehicles, plug-in hybrids and complete electric vehicles. Li-ion batteries has to be the energy storage technology when it comes to mobile applications.
Scarcity of lithium resource and the increased demand for it is initiating research in alternate battery technologies. Na-ion batteries are gaining research momentum due to their much better abundance in the Earth’s crust in comparison to lithium.
Regardless of the application, the discovery and optimization of high performance materials are critical to future breakthroughs for next-generation rechargeable batteries. For this, new classes of compounds should be explored and electrochemically characterized for gaining a better understanding of functional materials for battery research. This would be the focus of my research group in the coming future.
