Donald R. Sadoway is John F. Elliott Professor of Materials Chemistry in the Department of Materials Science and Engineering at MIT. His research seeks to establish the scientific underpinnings of technologies that make efficient use of energy and natural resources in an environmentally sound manner. This spans engineering applications and the supportive fundamental science. The overarching theme of his work is electrochemistry in nonaqueous media focused on these technological challenges: environmentally sound electrochemical extraction of metals, liquid metal batteries for stationary storage applications, and solid-polymer-electrolyte batteries for portable power applications.


Professor Sadoway is a co-founder of Ambri, Inc. (formerly Liquid Metal Battery Corporation), which is commercializing the liquid metal battery technology for grid-scale energy storage, and a co-founder of Boston Electrometallurgical Corp., which is commercializing molten oxide electrolysis for the production of metals. Both the liquid metal battery and molten oxide electrolysis were discovered by GroupSadoway at MIT.


Online videos of his lectures in general chemistry hosted by MIT OpenCourseWare extend Professor Sadoway’s impact on engineering education far beyond the lecture hall. Viewed 1.8 million times, his TED talk is as much about inventing inventors as it is about inventing the liquid metal battery. In 2012 Professor Sadoway was named by TIME magazine as one of the 100 most influential people in the world.
