Lithium-ion batteries take chemistry Nobel

Three scientists have been awarded the 2019 Nobel Prize in Chemistry for the development of lithium-ion batteries.

John B Goodenough, M Stanley Whittingham and Akira Yoshino share the prize for their work on these rechargeable devices, which are used for portable electronics.

At the age of 97, Prof Goodenough is the oldest ever Nobel laureate.

Olof Ramström, from the Nobel Committee, said lithium-ion batteries had "enabled the mobile world".

The trio will share the prize money of nine million kronor (£738,000).

The lithium-ion battery is a lightweight, rechargeable and powerful battery that is used in everything from mobile phones to laptops to electric cars.

The Nobel Committee said the device "created a rechargeable world".

It added: "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."

Göran K Hansson, secretary-general of the Royal Swedish Academy of Sciences, where this year's awards were announced, said their development enabled "a more sustainable world".

In addition to their use in electric vehicles, the rechargeable devices could also store significant amounts of energy from renewable sources, such as solar and wind power. (BBC)
