Arava Research Group is interested in fundamental electrochemical principles underlying in energy systems such as batteries, supercapacitors and fuel cells. We design variety of nanomaterials and understand their transport phenomena, electrode kinetics, electrocatalytic activity, and thermal and electrochemical stabilities under extreme environments using insitu Scanning Electrochemical Microscopy coupled Raman Spectroscopy (SECM-Raman) technique.

Our diverse activities in terms of applications include developing high energy and safe batteries for electric vehicles, micro-batteries to power micro-sensors, and flexible hybrid energy devices for wearable assistive technologies.

Our group is involved in exploring structural and functional concepts of nanomaterials and their composites for energy, health and environmental applications. We synthesize a variety of nanoscale structures such as carbon nanotubes; graphene; silicon nanorods; polymer, metal and metal oxide nanoparticles using chemical vapor deposition, sol-gel, hydrothermal and polymerization techniques. The connection between energy, sustainability, health and nanotechnology is an area that shows potential for great scientific and technological advances.
