For batteries
The Nobel Prize in Chemistry was awarded for the development of lithium-ion batteries
The Nobel Prize in Chemistry for 2019 will be awarded (from left to right) John B. Goodenough, Stanley Whittingham and Akira Yoshino for the development of lithium-ion batteries.
The broadcast of the ceremony of the announcement of the winners was conducted on the website of the award.
English chemist Stanley Whittingham worked on the development of energy production methods that could replace fossil fuels back in the 1970s. He made a titanium disulfide cathode for a lithium battery, which can include lithium ions. The anode was partially made of lithium metal and was capable of releasing electrons. However, due to the high reactivity of lithium metal, the battery turned out to be too explosive.
American John Goodenough improved the cathode by replacing titanium disulfide with cobalt oxide. Such a battery could create a voltage of up to four volts. Finally, Japanese chemist Akira Yoshino created the first viable lithium-ion battery by making an anode from polyacetylene and a cathode from lithium-cobalt oxide.
The official award ceremony will take place on the day of Alfred Nobel's death on December 10 in Stockholm. The laureates will receive an award from the hands of King Carl XVI Gustaf of Sweden. The amount of monetary remuneration in 2019 is about one million dollars for all winners of the chemistry prize.
