I gained PhD from the Advanced Electrochemical Materials Laboratory (AEML) at the National Chemical Laboratory (NCL), Pune in November 2018. During PhD, I designed synthesis strategies to increase the electrochemically active surface area of redox materials for application in flexible electrochemical capacitors. I also explored the field of electrocatalysis, fuel cells, zinc-air batteries, etc., for which I developed different Pt-free ORR electrocatalysts and learned fuel cell testing and MEA fabrication and performance optimization. After PhD, I joined the acclaimed Laboratory for Chemistry and Life Science at the Tokyo Institute of Technology (Tokyo Tech), Tokyo, Japan, in May 2019 to developmembrane-electrode-assembly for water electrolysis for hydrogen production. After my stint at Tokyo, I got the opportunity to explore the field of lithium batteries and gain further experience in new electrochemical methods and techniques at the Department of Chemical Engineering at University College London (UCL) and joined Lithium-Sulfur Technology Accelerator (LiSTAr) project funded by Faraday Institution as a postdoctoral research associate in October 2020. At UCL, I am investigating the application of the Distribution Function of Relaxation Times (DRT, Electrochemical Impedance Spectroscopy based method) for the performance diagnosis and estimation of state-of-charge and state-of-health in Lithium-sulfur Batteries.
