Nobel season opens with Medicine Prize

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.

  Nobel Prize in medicine goes to scientists who uncover how our cells use oxygen The discovery could mean new treatments for diseases.The Nobel Assembly at Karolinska Institute on Monday awarded the joint prize to William G. Kaelin, Jr. of Harvard University, Sir Peter J. Ratcliffe of Oxford University and Gregg L. Semenza of Johns Hopkins University.

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 Nobel Prize announcement is “really thrilling for the battery community,” says Kelsey Hatzell, a Lithium - ion batteries now perform much better than those on the market in 1991. Researchers are now developing different types of rechargeable lithium batteries , such as lithium-oxygen (SN

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.

Pioneers of lithium-ion batteries win the 2019 Nobel Prize in Chemistry

  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. RechargeableRechargeable 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.

" 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

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.)

Flight attendants warn of "catastrophic" fire risk from e-cigarettes

  Flight attendants warn of FAA data shows at least 48 e-cigarette related smoke or fire incidents at airports or on planes . That's more incidents than laptops and tablets, cell phones, battery chargers or spare batteries. An FAA test video shows why lithium-ion batteries have been banned in checked luggage. If a battery fails and enters what's called thermal runaway, it can burn so hot that the plane's fire suppression system can't put it out. In 2016, the FAA banned the Samsung Galaxy Note 7 smartphone due to its lithium batteries starting fires.

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.
