Read more about our research interests in our Manifesto. Our research is enabled by a combination of data/computational scientists, chemists, and engineers.
DATA SCIENCE FOR NEW ELECTROLYTES
We use AI and ML tools to generate new ideas for electrolyte compounds for next generation batteries as well as investigate novel solvation behavior for CO2 electrocatalysis. Our work involves using Natural Language Processing (NLP) tools (as well as manual extraction) to develop a database of experimentally measured electrolyte properties. ML models can then be made to correlate accessible electrolyte features (e.g., molecular structure) to properties such as conductivity and stability. This work is often done with data science and computational collaborators.
NEW ELECTROLYTE SYNTHESIS
Our projects involve the synthesis of new small molecules, polymers, and hybrid solid state electrolytes that can be incorporated in next generation batteries (lithium metal, solid state batteries, and multivalent), and for CO2 electroreduction.
ELECTRODE:ELECTROLYTE INTERFACE CHARACTERIZATION
Our work strives to correlate bulk electrolyte structure (e.g., solvation) to electrochemical reactions (desired and undesired) that occur at the electrode:electrolyte interface. Among many spectroscopic tools, we utilize microcalorimetry for kinetic and thermodynamic quantification, and NMR (solid and solution state) for chemical specificity.
HIGH ENERGY DENSITY BATTERIES
Our newly designed electrolytes coupled with our understanding of ion transport and electrochemical degradation will enable the fabrication of batteries with high energy density and longer cycle life. Right now, we are focused on lithium metal batteries (with liquid and hybrid solid state electrolytes), high voltage lithium-ion, and multivalent batteries.
SELECTIVE AND EFFICIENT ELECTROCATALYSIS
By understanding (and controlling) solvation effects in electrocatalytic media, we are at the forefront of designing highly selective and efficient electrochemical reactors for integrated carbon dioxide (CO2) capture and conversion to valuable products such as chemicals.
