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 96, Prof Goodenough is the oldest person to win the award.

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

The awards were announced at the Royal Swedish Academy of Sciences in Stockholm.
