The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Chemistry 2019 to John B. Goodenough, of The University of Texas at Austin, USA, M. Stanley Whittingham, of Binghamton University, State University of New York, USA, and Akira Yoshino of Asahi Kasei Corporation, Tokyo, Japan, and Meijo University, Nagoya, Japan "for the development of lithium-ion batteries."
The Nobel Prize in Chemistry 2019 rewards the development of the lithium-ion battery. This lightweight, rechargeable and powerful battery is now used in everything from mobile phones to laptops and electric vehicles. It can also store significant amounts of energy from solar and wind power, making possible a fossil fuel-free society.
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. Lithiumion batteries have also enabled the development of long-range electric cars and the storage of energy from renewable sources, such as solar and wind power.
The foundation of the lithium-ion battery was laid during the oil crisis in the 1970s. Stanley Whittingham worked on developing methods that could lead to fossil fuel-free energy technologies. He started to research superconductors and discovered an extremely energy-rich material, which he used to create an innovative cathode in a lithium battery. This was made from titanium disulphide which, at a molecular level, has spaces that can house -- intercalate -- lithium ions.
The battery's anode was partially made from metallic lithium, which has a strong drive to release electrons. This resulted in a battery that literally had great potential, just over two volts. However, metallic lithium is reactive and the battery was too explosive to be viable.
John Goodenough predicted that the cathode would have even greater potential if it was made using a metal oxide instead of a metal sulphide. After a systematic search, in 1980 he demonstrated that cobalt oxide with intercalated lithium ions can produce as much as four volts. This was an important breakthrough and would lead to much more powerful batteries.
With Goodenough's cathode as a basis, Akira Yoshino created the first commercially viable lithium-ion battery in 1985. Rather than using reactive lithium in the anode, he used petroleum coke, a carbon material that, like the cathode's cobalt oxide, can intercalate lithium ions.
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.
Lithium-ion batteries have revolutionized our lives since they first entered the market in 1991. They have laid the foundation of a wireless, fossil fuel-free society, and are of the greatest benefit to humankind.

The use of lithium batteries is growing exponentially – thanks to their light weight, performance and relatively low cost.
But shipping lithium batteries has proven dangerous, being blamed for a number of aircraft crashes, as well as devastating fires if batteries are not handled, stored or transported in the correct manner.
Whilst this has led to the rise of specialist packaging that have been tested to UN standards – there are many misconceptions surrounding the topic. Many are also unaware that such stringent laws and guidelines even exist.
Here is the link to all the regulations, when sending a shipment with lithium batteries: IATA lithium batteries regulations.
DGM Luxembourg is specialized and up to date with all regulations when sending shipments with lithium batteries. There is no place for mistakes and for that reasons, we are using DG Office, online software solution that contains everything to manage all your dangerous goods related activities.
