The trio will share the prize for their work on "the development of lithium-ion batteries," according to the Nobel committee."Lithium-ion batteries have revolutionized our lives and are used in everything from mobile phones to laptops and electric vehicles," tweeted the committee.

John B. Goodenough, M. Stanley Whittingham and Akira Yoshino were jointly awarded the Nobel Prize in Chemistry for their development of lightweight lithium - ion batteries , the Royal Swedish Academy of Sciences announced on Wednesday in Stockholm.

Lithium - ion batteries have long been tipped for the award, not least since they have This is the 111th Nobel prize in chemistry – the first was awarded in 1901. Only five women have been awarded the prize The peace prize winner will be announced on Friday, followed by economics on Monday.

You’re likely reading this news story on a device powered by the invention that won this year’s Nobel Prize in chemistry: lithium-ion batteries. The award went to John Goodenough, professor at the University of Texas at Austin; Stanley Whittingham, professor at the Binghamton University; and Akira Yoshino, professor at Meijo University, each of whom made significant contributions to the development of the world’s most powerful battery.

The lithium-ion battery story started during the oil crises of the 1970s, when companies like Exxon began investing in oil alternatives and new energy sources. Whittingham, a materials scientist, was hired to develop batteries.

  Pioneers of lithium-ion batteries win the 2019 Nobel Prize in Chemistry This year's Nobel Prize in Chemistry has been awarded to three scientists credited with the invention of the rechargeable lithium-ion battery. John B Goodenough of the University of Texas at Austin, M Stanley Whittingham of Binghamton University and Akira Yoshino of Meijo University will receive equal shares of the 9m Swedish kronor ($905,000) prize, which was announced today by the Royal Swedish Academy of Sciences in Stockholm.

Every battery, from the first one invented in 1799, is made of two electrodes—an anode and a cathode—dipped in a conductive solution (called an electrolyte) with a separator that controls the flow of the electric charge. At Exxon, Whittingham realized that lithium metal could be used as an anode, as long as the highly reactive metal was encased and not brought in contact with air or water. And his earlier work had showed titanium disulphide could be used as a cathode to store charged lithium atoms, called lithium ions.

After tweaking and testing, in 1976, Whittingham and his colleagues showed that combining lithium metal and titanium disulphide could not just make a battery, but one that was rechargeable. It brought lighter lithium-based batteries in competition with the bulky rechargeable lead-acid batteries that were used in cars to power electrical needs.

Nobel Prize in chemistry recognizes work on lithium-ion batteries that power our lives

  Nobel Prize in chemistry recognizes work on lithium-ion batteries that power our lives Three scientists are being honored for creating a "rechargeable world."That is, this year's winner are the scientists behind the lithium-ion battery. The Royal Swedish Academy of Sciences is giving John B. Goodenough, M. Stanley Whittingham and Akira Yoshino the award for creating a "rechargeable world," according to a statement Wednesday.

" Lithium - ion batteries have revolutionized our lives since they first entered the market in 1991. They have laid the foundation of a wireless, fossil fuel-free society, and are of the greatest benefit to humankind," the Nobel Prize foundation said. The three laureates will share the Nobel prize of 9

Lithium - ion batteries are used globally to power the portable electronics that we use to communicate, work, study, listen to music and search for knowledge. The foundation of the lithium - ion battery was laid during the oil crisis in the 1970s. Stanley Whittingham worked on developing methods that could

The trouble was, Whittingham’s battery didn’t last very long. During its cycles of charging and discharging, lithium metal had a tendency to form dendrites—long string-like structures—that could cause a short circuit and blow up the battery.

At about the same time, the oil crises ended and a glut of cheap fuel was back. Exxon shut down its battery research. But Whittingham’s working prototype and other work on battery materials ignited wider interest in the field.

One of the researchers inspired by the work was John Goodenough, then at the University of Oxford, who found that instead of titanium disulfide as a cathode, it was better to use cobalt oxide. The cobalt-based battery was able to store more energy and do so more safely.

Meanwhile, on the other side of the world, Yoshino was working in Japan for the chemicals company Asahi Kasei. He found that, instead of using lithium metal, it was better to use graphite as an anode. The material stored fewer lithium atoms, but it also substantially reduced fire risks. (While the use of lithium metal was dropped, the battery still shuttled lithium ions between the electrodes—thus the name lithium-ion battery.)

Chemistry Nobel Hails Work on Batteries That Changed Society

  Chemistry Nobel Hails Work on Batteries That Changed Society Stanley Whittingham of the U.K., Japan’s Akira Yoshino and German-born John Goodenough won the 2019 Nobel Prize in Chemistry for the development of lithium-ion batteries that have changed everyday life with rechargeable power sources enabling mobile phones and electric cars. Such batteries have “revolutionized our lives” since they first entered the market in 1991, the Royal Swedish Academy of Sciences said in a statement on Wednesday. “They have laid the foundation of a wireless, fossil fuel-free society, and are of the greatest benefit to humankind.

Rechargeable lithium - ion batteries can be found in pretty much everything from mobile phones to electric vehicles, and can store significant amounts of energy from solar and wind power. Given their prominent place in everyday life, and the fact that they were first developed in the 1970s, many would

Like all liquid ion batteries , lithium - ion batteries contain two electrodes—an anode and a cathode—separated by a liquid electrolyte that allows ions to move back and forth. During discharge, stocks of lithium atoms at the anode give up electrons to generate a current for an external circuit.

Yoshio Nishi and Keizaburo Tozawa, both working at Sony, put in the hard work to convert the scientific ideas of Whittingham, Goodenough, and Yoshino into the world’s first commercial lithium-ion battery in 1992. It proved an instant success: Sony sold 3 million units in 1993 and 15 million in 1994.

Since then, engineering and materials developments have made lithium-ion batteries both cheaper and more versatile. They are now in use in everything from tiny devices like wireless earphones to giant ones like electric ships—and, of course, smartphones and electric cars. They can also be used to store renewable energy for later use and to power electric planes.

Crucially, lithium-ion batteries are helping lower greenhouse-gas emissions, helping tackle humanity’s greatest challenge in climate change. Ironically, that which began its life in an oil company has now become a threat for the entire oil industry.
