Research Engineer at South 8 Technologies
Even after 3 years of researching and engineering batteries I still find them almost magical. They are essentially nanoscale sponges absorbing practically invisible lithium-ions at the thermodynamic and kinetic limits of the liquid soup of electrolyte transporting them and continue to excite both me for the science and an insanely rapid growing market for their capabilities and hope of a greener future.

In my current role as a Research Engineer, I get to directly study that magic by researching and developing South 8 Technologies' novel liquefied gas (LiGas) electrolyte ranging from testing various electrolyte formulations/additives to optimizing for specific electrodes or use cases. Concurrently, I help train and educate Research Associates on cell construction and electrochemistry fundamentals, as well as direct cell builds for various projects. I have experience using and interpreting data from cyclic voltametry (CV), electrochemical impedance spectroscopy (EIS), conductivity measurements and general battery cycling (life cycle, rate and temperature capabilities) on Biologic and Maccor cyclers.

I've also had experience conducting UL safety testing, including thermal runaway, temperature, short circuit and overcharge/discharge testing of both modules and packs used in electric vehicles during my time at Flux Power. During my graduate studies, I also extensively studied lithium metal anodes, first authoring a paper on optical in-situ characterization of lithium plating and stripping, took multiple courses on electrochemistry and materials at UC San Diego and established and effectively managed a battery lab at SDSU.

My background in Mechanical Engineering has also provided a unique ability to critically solve problems through engineering and building practical solutions that are not always available commercially.

As I continue to grow in my career, I hope to keep learning about the world of electrochemical devices, research and develop interesting new technologies, educate and lead the next generation of innovators and researchers and ultimately help contribute to a greener and cleaner future for us all.

This work enables highly “uniform” and “reversible” deposition of Li metal in carbonate electrolytes through a one-time rapid oxidation and reduction (ROAR) treatment. Over the years, Li metal has been plagued with irreversible dendritic growths that create isolated and unusable structures called “dead Li”. Accumulation of dead Li negatively impacts the ion transport, performance, and safety of Li metal batteries. To address this long-standing problem, we have developed an in situ process to uniformly create reversible Li deposits. Our results demonstrate that a combination of high-voltage pulses, which rapidly oxidize and reduce Li in both directions (ROAR treatment), leads to strikingly more homogeneous morphology and eliminates reaction pathway transitions. We validate that ROAR treatments eliminate traditional “mossy dendrites” under extended cycling (<250 cycles) in standard carbonate-based electrolytes. Moreover, ROAR treatments create a 500% reduction in overpotential for electrodissolution/deposition and eliminate “peaking” voltage behavior.
