Who Really Invented the Rechargeable Lithium-Ion Battery?

Cars That Think

Fifty years after the birth of the rechargeable lithium-ion battery, it’s easy to see its value. Did Exxon invent the rechargeable lithium battery? The battery’s performance was also unprecedented: It was both rechargeable and very high in energy output. It’s used in billions of laptops, cellphones, power tools, and cars.

Goodenough perspective on Li-ion batteries; in transportation, PHEVs for the near-term, longer term requires new electrochemical strategies

Green Car Congress

John Goodenough at the University of Texas at Austin and colleague Kyu-Sung Park have written a perspective paper on Li-ion batteries (LIBs), published in the Journal of the American Chemical Society. More recently, at the University of Texas, Austin, Dr. Goodenough patented a new class of iron phosphate materials. Earlier post.).

Fialka Wall Street Journal March 26, 2007 AUSTIN, Texas -- Of all the plans cooked up by cities to combat pollution and global warming, the one hatched here is among the most ambitious -- and, some say, one of the more quixotic. Some utilities will buy extra power that their customers produce by home solar panels. Department of Energy.
