Scientific research depends on far-sighted people who can think outside the box. Such research is key to our understanding of the universe, the development of physical science, and our ability to enjoy world-changing technology products.
One such far-sighted people is John B. Goodenough, now 97, who developed the lithium-ion battery (锂离子电池) in the 1970s. Now, decades after his important breakthrough, Goodenough enters history as the winner of the Nobel Prize in chemistry of 2019. He shares the award with Akira Yoshino, 71, and M Stanley Whittingham, 77, who co-created the battery with Goodenough at the University of Oxford.
“Through their work, they have created the right conditions for wireless and fossil fuel-free society, and brought the greatest benefit to humankind,” said the Nobel Foundation.
Yet despite this rechargeable battery benefiting billions of people around the world every day, we too often take science for granted.
Indeed, the Nobel Committee - and even Goodenough himself - hadn’t seemed to appreciate the impact his research would have on future generation. “At the time we developed the battery, it was just something to do,” Goodenough told the Times Newspaper earlier this year. “I didn’t know what electrical engineers would do with the battery. I really didn’t anticipate cellphones, camera and everything else.”
As many have agreed - and Goodenough shows - the science of today is the technology of tomorrow. Goodenough’s invention is evidence of imagination being put to work for the greater good. For that, his research is good enough at last.
1.Why does Goodenough enter history?
