Expanding the voltage stability window of aqueous Mn-based batteries and elucidating Mn coordination chemistry in selected ligands to improve cyclability for grid-wide energy storage.

Stanford Aqueous Battery Consortium (ABC)
Advanced Alkaline Hydrogen Electrolyzer

Developing PGM-free catalysts and using impedance spectroscopy to reveal HER mechanisms, dielectric and transport behavior, and corrosion pathways that enable long-life alkaline electrolyzers.

DOE-funded
Liquid Fuel & Seawater Electrolysis

Direct electrolysis of seawater, chemical hydrides, and biofuels (methanol, ethanol, glycerol, ammonia borane, NaBH₄) to generate clean hydrogen and high-value chemicals.

High Entropy Alloys (HEAs)

Computational identification, synthesis, and characterization of transition-metal HEAs for water splitting, battery electrodes, and corrosion-resistant electrocatalysts.

Non-Pt Oxygen Electrocatalysts

Exploring non-Pt catalysts — and alternative electrode reactions — to reduce potential losses at the oxygen electrode in liquid fuel cells.

Biomass Valorization for Energy Storage

Valorizing V. rotundifolia (Muscadine) grape pomace into high-performance carbon electrode materials for supercapacitors and Li-ion batteries.
