Research Interests

Hatzell's group is interested in emerging decarbonization technologies for transportation, fuel, and direct air capture applications. The group has a significant focus on energy storage (batteries/thermal) and is interested at using non-equilibrium x-ray techniques to probe materials during in situ and operando experimentation.  Hatzell's group has been examining novel inorganic and hybrid solid electrolytes for next generation solid state batteries.
