  • Three scientists have been awarded the 2019 Nobel Prize in Chemistry for the development of lithium-ion batteries.
  • The Prize includes 9-million kronor ($918,000) cash award, a gold medal and a diploma.

The Nobel Winners

  • John D. Goodenough
  • Stanley Whittingham
  • Akira Yoshino

Award Winning Discovery

  • In the early 1970s, Whittingham used lithium’s enormous drive to release its outer electron when he developed the first functional lithium battery.
  • Goodenough doubled the lithium battery’s potential, creating the right conditions for a vastly more powerful and useful battery.
  • Yoshino succeeded in eliminating pure lithium from the battery, instead basing it wholly on lithium ions, which are safer than pure lithium.
  • This made the battery workable in practice.
  • The result was a lightweight, hardwearing battery that could be charged hundreds of times before its performance deteriorated.
  • The advantage of lithium-ion batteries is that they are not based upon chemical reactions that break down the electrodes, but upon lithium ions flowing back and forth between the anode and cathode.

Significance

  • Lithium-ion batteries have revolutionized human lives since they first entered the market in 1991.
  • Today, lithium batteries are used everywhere from mobile phones to electric vehicles.
  • It is also used to store significant amounts of energy from solar and wind power, making possible a fossil fuel-free society.
