Betar Maurkah Gallant is an American engineer who is an associate professor at Massachusetts Institute of Technology. Her research investigates the development of new materials for batteries.




Early life and education


Gallant grew up in a scientific family: her mother worked in urban planning and her father worked in engineering. While she was a teenager, Gallant's father died from an illness and she started to read his old physics textbooks. Gallant was an undergraduate at Massachusetts Institute of Technology, and took part in a Undergraduate Research Opportunities Program with Yang Shao-Horn. Together they explored electrochemistry. During 2009, Gallant joined the United States Department of Energy Energy Technology Program, where she led the Regaining our Energy Science and Engineering Edge initiative. RE-ENERGYSE was developed by the Obama White House to educate young Americans in clean energy research. Gallant completed her doctoral research at Massachusetts Institute of Technology, where she developed carbon nanotube structures for lithium batteries supervised by Shao-Horn.




Research and career


Gallant moved to California Institute of Technology, where she worked as a Kavli Nanoscience Fellow. She was appointed to the faculty at MIT in 2015. She initially investigated the incorporation of carbon dioxide into batteries as a strategy to mitigate greenhouse gases. This research led her to investigate the electrochemical reactions of carbon dioxide, and propose new strategies to simplify carbon capture. She pioneered the use of electrochemical strategies to separate carbon dioxide from amine, the sorbent molecule used in carbon capture and storage. She showed that by separating the carbon dioxide and the amine, it was possible to extend the reaction, eventually making a stable solid form of carbon dioxide that was easy to separate. Gallant has studied the mechanisms that underpin the solid electrolyte interphase (SEI).
Despite non-rechargeable batteries being critical in medical devices like pacemakers, so far, innovation in battery research has mainly considered rechargeable batteries. Gallant decided to address this research gap, developing long-lasting non-rechargeable batteries based on fluorinated electrolytes.
