Battery Researcher
I develop electrolytes, cathode materials, and electrode processing methods for batteries. My work connects materials development with electrochemical testing, from coin cells to 3 Ah pouch cells.

My research examines how material composition, interfacial chemistry, and electrode processing affect battery performance. The work spans lithium-ion, lithium-metal, solid-state, and structural batteries, with an emphasis on connecting laboratory results to larger cell formats.

My scale-up work connects materials development with electrode processing and cell validation. This includes electrolyte preparation in batches up to 2.5 kg and cell development from coin cells to 3 Ah pouch cells.
Carbon-fiber electrodes for batteries designed to store energy and carry mechanical load. The carbon fiber serves as both the anode and current collector and is paired with a non-flammable ionic-liquid electrolyte.
Adding 1 wt% LiPO2F2 to an LHCE with 30% TTE improved LMR/graphite full cells at 0, 25, and 45 °C and suppressed Mn and Ni dissolution from the cathode.
A dual-salt LHCE kept 69.1% capacity after 450 cycles at C/3 in NMC811 lithium-metal cells. The standard electrolyte kept 25.5%.
A non-flammable ionic liquid, 1 M LiTFSI in PYR13-FSI, kept 83% capacity over 100 cycles in LFP/carbon-fiber cells built without copper or aluminum foil.
A scalable wet-chemical route to nano-LFP from metallic iron: 160 mAh/g initially, over 90% capacity after 200 cycles, and about 130 mAh/g at 10C charging. Recycled iron cuts raw material cost by nearly 30%.
SiOx/C-shelled silicon anchored on reduced graphene oxide charges and discharges at 10C (about 18.8 A/g) and suppresses contact-impedance growth.
Selective leaching of transition metals from spent NMC111, with the residue upcycled into a single-crystal Li- and Mn-rich cathode.
10 to 20 wt% LLZTO gave the most stable lithium interface, with symmetric cells running 1,000 cycles. At 30 wt%, direct Li/LLZTO contact degraded it.
A Li3N layer about 3 µm thick, grown on lithium in one gas-phase step inside a nitrogen glovebox, suppresses voids and microcracks at the argyrodite interface.
3 wt% Sb2S5 doping raised ionic conductivity by 36%, suppressed moisture-induced decomposition, and reached a critical current density of 1.7 mA/cm2.
Li–Mg alloys with 0.5 to 1.5 at% Mg gave the best interfacial stability, with critical current density near 1.8 mA/cm2 at 1.5 at%.
SiOx-shelled nano-silicon anchored on reduced graphene oxide delivered 44.8% more capacity at 1C charging than plain nano-silicon in sulfide all-solid-state cells.
I am a Ph.D. candidate in Materials Science and Engineering at The Ohio State University. My research focuses on electrolytes, electrode materials, and processing for lithium-ion, lithium-metal, solid-state, and structural batteries.
I work with automotive and materials-industry collaborators on materials development, cell fabrication, and failure analysis. My experience includes coin and pouch cells, dry-room processing, and electrolyte scale-up.
I’m interested in battery R&D roles and research collaborations involving materials development, electrode processing, and cell scale-up.
