Pioneers of lithium-ion batteries win the 2019 Nobel Prize in Chemistry

A Harvard doctor is one in trio of scientists awarded the Nobel Prize in medicine. What they discovered is amazing.

"We are delighted that APS Fellow John Goodenough, APS Life Member M. Stanley Whittingham, and Akira Yoshino have been recognized for their pioneering work".

Goodenough said he is grateful he was not forced to retire at age 65.

Two APS members are among the recipients of 2019 Nobel Prize in Chemistry.

He said he already called his wife and told her about the prize, leaving her surprised.

Akira Yoshino is the fourth Award finalist to be recognised by the Nobel Academy for his outstanding contribution to science. We have gained access to a technical revolution. Yoshino's research on ensuring chemical stability crowned the current lithium-ion battery.

Research on better stores of energy started in the early 1970s amid the oil crisis.

The invention of the lithium-ion battery has had a deep influence on modern life.

His work founded the basis of John Goodenough's 90s demonstration that cobalt oxide with intercalated lithium ions can produce as much as four volts. The batteries, therefore, were too explosive to be viable. That's where Yoshino's work in the 1980s came in. And it was Akira Yoshino who "succeeded in eliminating pure lithium from the battery, instead basing it wholly on lithium ions, which are safer than pure lithium". He added another material in one electrode that reduced the potential for fires. He developed a battery that combined lithium and titanium disulfide.

Building on this foundation could enable broader use of renewable energy sources that generate power at variable times.

The prize amount is 9 million Swedish krona (about 1 million USA dollars) and will be shared equally among the Laureates.

The three will receive the prize from King Carl XVI Gustaf at a formal ceremony in Stockholm on December 10, the anniversary of the 1896 death of scientist Alfred Nobel who created the prizes in his last will and testament.

The announcement kicked off Nobel week.

The 2019 Nobel Prize in Chemistry will be announced Wednesday, a day after the Physics award was given to a Canadian-American cosmologist and two Swiss scientists.

The global award in the Physiology or Medicine was jointly awarded to William G Kaelin Jr, Peter J Ratcliffe and Gregg L Semenza for their discoveries of how cells sense and adapt to oxygen availability. It said Semenza, Ratcliffe and Kaelin found "the molecular switch for how to adapt" when oxygen levels in the body vary, noting that the most fundamental job for cells is to convert oxygen to food and that cells and tissues constantly experience changes in oxygen availability.
