3 win Nobel in Chemistry for work on lithium-ion batteries

SeattlePI.com Wednesday, 9 October 2019 ()
STOCKHOLM (AP) — Three scientists won the Nobel Prize in Chemistry on Wednesday for their work developing lithium-ion batteries, which have reshaped energy storage and transformed cars, mobile phones and many other devices — and reduced the world's reliance on fossil fuels that contribute to global warming.

The prize went to John B. Goodenough, 97, a German-born engineering professor at the University of Texas; M. Stanley Whittingham, 77, a British-American chemistry professor at the State University of New York at Binghamton; and Japan's Akira Yoshino, 71, of Asahi Kasei Corporation and Meijo University.

Goodenough is the oldest person to ever win a Nobel Prize.

The three each had a set of unique breakthroughs that cumulatively laid the foundation for the development of a commercial rechargeable battery.

Lithium-ion batteries — the first truly portable and rechargeable batteries — took more than a decade to develop, and drew upon the work of multiple scientists in the U.S., Japan and around the world.

The work had its roots in the oil crisis in the 1970s, when Whittingham was working on efforts to develop fossil fuel-free energy technologies. He harnessed the enormous tendency of lithium — the lightest metal — to give away its electrons to make a battery capable of generating just over two volts.

By 1980, Goodenough had doubled the capacity of the battery to four volts by using cobalt oxide in the cathode — one of two electrodes, along with the anode, that make up the ends of a battery.

But that battery remained too explosive for general commercial use and needed to be tamed. That's where Yoshino's work in the 1980s came in. He substituted petroleum coke, a carbon material, in the battery's anode. This step paved the way for the first lightweight,...
