Silicon Anodes: Where to Next?
Silicon has received significant attention as a viable alternative to graphitic carbon as the negative electrode in lithium-ion batteries due to its high capacity and availability. More recently it has become apparent that substantial lifetime issues exist in cells with silicon anodes even when not cyclizing. This raises major questions as to the parasitic reactions that occur at the silicon anode. This talk will focus on the challenges that are faced in the development of silicon anodes for lithium ion batteries.
Biography: Dr. Burrell received his Ph.D. degree in chemistry in 1990 from the University of Auckland, New Zealand. Then he became Chair of Synthetic Chemistry in 1998-2001 at Massey University, New Zealand; and scientist at Los Alamos National Laboratory during 2001-2010 where he established new programs in materials chemistry including being one of the leads for the Chemical Hydrogen Storage Center of Excellence. During 2011-2016, Dr. Burrell was leading the Department of Electrochemical Energy Storage at Argonne National Laboratory, where he was the Department Head, PI in the Joint Center for Energy Storage Research and the Voltage Fade Project, and PI for the High Energy-High Voltage Deep Dive and the Intermetallic Anodes Consortium. In 2016 Dr. Burrell joined the National Renewable Energy Laboratory as Chief Technologist for Energy Storage.
