Kelsey Hatzell is an American materials scientist who is a professor at Princeton University. Hatzell studies new materials for sustainable technologies, with a focus on next-generation energy storage. She is interested in the nanoscale phenomena responsible for battery failure.

Early life and education

[edit]

Hatzell studied economics at Swarthmore College and mechanical engineering at Pennsylvania State University.[1] She moved to Drexel University for her doctoral research, where she studied flowable electrodes for water and energy technologies with Yury Gogotsi.[2] Her research involved electrochemistry, materials and colloidal science to create new electrode structures. She developed carbon-based and manganese oxide materials for scalable solid-state energy storage systems.[2] After graduating, she moved to the Lawrence Berkeley National Laboratory, where she developed soft and hard x-ray techniques to understand the properties of polymers.[3]

Research and career

[edit]

Hatzell was appointed an assistant professor at Vanderbilt University.[3][4] Hatzell joined Princeton University in 2021.[citation needed] Her research considers new materials for sustainable technologies, with a focus on solid-state and redox flow batteries. She is particularly interested in why batteries fail.[5] She identified that irregularities in electrolytes impacted the movement of ions, which could cause battery failure if the ions all migrated to particular locations.[6] Hatzell has created inorganic membranes for high energy density batteries and grid storage.[7]

Hatzell has developed strategies to minimize the costs of direct air capture systems, which generally require energy-intensive operating protocols to reduce the impact of carbon emissions and remove them from the atmosphere. These systems conventionally rely on heat or pressure changes to release captured carbon dioxide into storage (e.g. solvents heated to high temperatures). Hatzell developed an ion-exchange resin, which efficiently capture carbon dioxide at low humidity and release it at high humidity – without the need for high temperatures.[8]
