All things electrochemistry

interfaces in Batteries

We are interested in understanding the origins of degradation in high energy and high power battery materials for electric vehicle and grid storage applications, using a suite of electroanalytical and spectroscopic tools. Further, we seek to develop chemical surface modification methodologies for these battery materials to suppress degradation pathways and enhance their long term cycling performance.

multi-electron redox

We use state-of-the-art computational tools to screen molecular electrocatalyst candidates for energy-relevant transformations such as the CO2RR, ORR and NRR, based on the free energies of catalytic intermediates. The in-silico predictions are supplemented with experimental synthesis, electrochemical and spectroscopic measurements in a feedback loop. We are particularly interested in transition metal complexes that can catalyze multi-electron redox processes at low overpotentials.

FLEXIBLE neural probes

A key challenge associated with building chronic implantable neural microelectrodes is finding high-charge injection materials that can resist corrosion and exhibit superior cycling ability. PEDOT, Platinum, Iridium Oxide, Tantalum Oxide, Titanium Nitride, and Ruthenium Oxide are popular electrode material choices. However, each of them comes with their own shortcomings. We are developing bio-compatible, composite charge injection materials with superior corrosion resistance, charge injection capability and long cycle life, for medical device applications.
