Nobel Chemistry Prize – level 2
15-10-2019 07:00
John B. Goodenough, M. Stanley Whittingham, and Akira Yoshino won this year’s Nobel Prize in chemistry. They created a lithium-ion battery. It is a device that people across the world use every day in their electronic devices such as cellphones, laptops, or electric vehicles.
Wittingham developed the first battery in the 1970s. However, it was too explosive. Later, Goodenough doubled the voltage of the battery. In 1985, Yoshino created the first lithium-ion battery which could be charged over and over.
The Nobel Prize Committee says that this battery is a great benefit to all people. It means the start of a wireless society without fossil fuels.
Difficult words: device (an electronic thing with a specific purpose), voltage (when electricity is measured in a term called volts), fossil fuels (people use coal, oil, and gas for energy but they make pollution).
You can watch the original video in the Level 3 section.
