| 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. | |
