We are working on lithium and sodium-ion batteries at Electrochemical Research Laboratory (ECRL) in the Department of Chemical Engineering at Indian Institute of Technology Kharagpur. Our main focus is to develop new generation post-lithium-ion batteries for commercial batteries. We do our research from basic electrochemistry to synthesis of different type functional nano, micro and bulk materials to prototype development.
Currently, we are doing research on

Sodium-ion batteries, electrode materials synthesis, characterization, fabrication
Electrolyte optimization for sodium-ion batteries
Prototype development of sodium-ion batteries
Lithium-ion batteries, electrode materials synthesis, characterization, fabrication
Multivalent batteries, electrode materials synthesis, characterization, fabrication
Commercial level battery research

We are always looking for collaborative and interdisciplinary research.
