Professor Sadoway's research
seeks to establish the scientific underpinnings for 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.
Specific topics in applied
research are the following: environmentally sound electrochemical extraction
and recycling of metals, lithium solid-polymer-electrolyte batteries,
advanced materials for use as electrodes, separators, and walls in fused-salt
electrolysis cells and batteries, electrochemical sensors, electrochemical
synthesis of thin films of compound semiconductors in fused-salt and
cryogenic media, and electrochemically controlled superconducting devices.
Related to these are the
following topics in fundamental research: the physical chemistry and
electrochemistry of molten salts (including molten oxides), cryogenic
electrolytes, and solid polymer electrolytes.

Tech Talk reported on "Picturing to Learn," an educational technique that encourages students to draw as they learn new concepts; 3.091 used the technique in 2005.
The Boston Globe reported on Prof. Sadoway's battery research in stories on Feb. 20, 2006 and Aug. 1, 2005. Prof. Sadoway and 3.091
were profiled in The
Tech in October 2002. His research on highly flexible
batteries was mentioned in an article in the July 2003 Technology
Insider. The January 2004 Deshpande
Center newsletter profiled Prof. Sadoway's research in
steelmaking. The Feb. 6, 2004 Tech interviewed Prof. Sadoway. He was recently the emcee of the
annual hamentashen vs. latke debate at MIT (see Tech
Talk for more details). Technology
Insider wrote about his work with rechargeable lithium
batteries (April 2004) and about his efforts to develop a
means of making a carbon-free steel having byproducts of only
oxegen and molten iron (May 2004).
