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. "We have gained access to a technical revolution. The laureates developed lightweight batteries of high enough potential to be useful in many applications." 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.
