A Long and Productive Life On his 96th birthday today, John Goodenough and his research team’s latest findings are the subject of much speculation.  He, fellow scientist Maria Braga, and his research team have created a battery claimed to be three times as energy dense as existing lithium-ion contemporaries, but exhibiting the counterintuitive property of improving with repeated charging cycles. Goodenough’s career began in 1943 (a year after your editor was born) with the award of his bachelor’s degree in mathematics from Yale University, followed his master’s and Ph.D. in physics from the University of Chicago in 1951 and 1952 respectively.  He worked at MIT and in 1976, left to become head of Oxford University’s Inorganic Chemistry Laboratory from 1976 …

While much of battery research goes into crafting the ultimate anode, cathode or electrolyte, there seem to be few efforts, at least to outside observers, of integrated approaches to making a better total battery.  That may change soon, with the Department of Energy announcing formation of a new Joint Center for Energy Storage Research (J-CESR, or J-Caesar).   Dr. Steven Chu, U. S. Secretary of Energy, has established the Center at Argonne National Laboratory with a budget of $120 million over five years to create a battery five times more powerful and five times cheaper than today’s norms – all within five years. For those of us who’ve grown wary of those “breakthough” announcements that almost always include the line, …
