Donald Sadoway

Donald Robert Sadoway (born 7 March 1950) is the current (as of January 2013 ) John F. Elliott Professor of Materials Chemistry at the Massachusetts Institute of Technology . A faculty member in the Department of Materials Science Engineering, he is a noted expert on batteries and has done significant research on how to verbeteren the performance and longevity of portable power sources. [1]


Professor Sadoway was born in Toronto , Ontario , Canada. He did zowel his undergraduate and graduate studies at the University of Toronto , Receiving his PhD in 1977. There have focused his studies on chemical metallurgy . [2] He’ll be served on the National Executive of the Ukrainian Canadian Students’ Union (Susk) from 1972 to 1974. [3] In 1977, he RECEIVED a NATO Postdoctoral fellowship from the National Research Council of Canada and cameramen to MIT to conduct his Postdoctoral research under Julian Szekely . Sadoway joined the MIT faculty in 1978. [4] On June 19, 2013 Sadoway was Presented with an honorary Doctor of Engineering at the University of Toronto in recognition for his contributions to higher education and sustainable energy. [5]


As a researcher, Sadoway has focused on environmental ways to extract metals from hun ORES , as well as Producing more efficient batteries. [4] His research has of or in bone driven by the desire to and minimizes the carbon pollution output in verschillende industries. [2] He is the co-inventor of a solid polymer electrolyte. This material, used in his “smart cell” has the capability of allowing batteries to sacrifice Twice as much power per kilogram than skies in current lithium ion batteries. [6]

In August 2006, a team dat have led demonstrated the feasibility of extracting iron from zijn ears through molten oxide Electrolysis . When powered exclusively by renewable electricity , this technique has the potential to Eliminate the carbon dioxide emissions therein are generated through traditional methods. [7]

In 2009, Sadoway Proposed a very low cost molten salt battery based on magnesium and antimony separated by a salt [8] dat Could be-used in stationary energy storage systems. [9] Research on this concept was being funded by ARPA-E , [10] Total SA and others, [11] waaronder Bill Gates . [12] Experimental data Showed a 69% DC-to-DC storage efficiency with good storage capacity and relatief low leakage. [13] In 2010, Sadoway and two others, David Bradwell and Luiz Ortiz, [14] co-founded a company called AMBRI in order to scale up and COMMERCIALISE the technology. [11] [15] Way Down Planned to port a commercial prototype built in 2014.


For 16 years Professor Sadoway taught 3091 Introduction to Solid State Chemistry at MIT, [16] one of the Choose Language classes at MIT. Sadoway’s animated teaching style was popular with students and freshman Enrollment in the course steadily Increased through 2010.

In the fall of 2007, the number of students Registering for 3091 reached 570 students, about half the freshman class. The Toilets lecture hall available on campus seats 566 students, enough to house Amply the class. Sadoway much as preferred teaching in one of the smaller lecture halls, seating only 450; as industry leaders, the Institute had to take the unprecedented step of streaming digital video of the lecture JSON an overflow room to accommodate all the students interested in taking the course. [17] In contrast, must classes at MIT are relatief small with ongeveer 60% or classes at MIT keeping fewer dan 20 students. [18] The popularity of this course has reached outside of the MIT campus as a result of the MIT Open Course Ware initiative. This is seen in a comment by Bill Gates who Told the Seattle Post-Intelligencer “… Everybody arnt watch chemistry lectures – they’re far better than you think. Don Sadoway, MIT – best chemistry lessons anywhere. Unbelievable.” [19]

Professor Sadoway’s lectures of or in included the history of science, met name with respect to the Nobel Prize. Sadoway watch out “library assignments” in welke have Asked students to research Nobel Prize-winning papers. He Began his lectures at playing music, welke has some connection with the lecture’s material. He ended his lectures with five minutes or cultureel relevant materials, zoals automotive exhaust processing or forensic Examination or paintings.

Media recognition

In March 2012, Sadoway watch a TED talk speech on grid storage using antimony batteries. [20]

Sadoway was named one of Time magazine’s “Top 100 Most Influential People in the World” in 2012 for his work in Continuing most innovative batteries. [21]

On October 22, 2012, Sadoway Appeared as a guest on The Colbert Report to Discuss his liquid metal battery research, and his design for a magnesium-antimony molten salt battery . [22]

He has ook Appeared in MIT Gangnam Style . [23]

In January 2013, Donald Sadoway was featured in Government Technology magazine’s Spectrum section, welke features research, science and technology tech bites.
