The Nobel Committee represented by the Royal Swedish Academy of Sciences continued the tradition of awarding the most prestigious awards in the scientific world for the already known developments. Thus, the Nobel prize of 2019 in chemistry was awarded for the creation and commercialization of lithium-ion batteries.
Until the 1970s of the last century, mankind was not particularly interested in batteries, because fossil hydrocarbon fuel was easily accessible, cheap and with its help it was possible to manage any mechanisms. However, the oil crisis has changed the situation in many markets radically, making a number of traditional production processes simply unprofitable.
From this day intensive scientific research in the field of superconductors began. The greatest success in this direction was achieved by Stanley Whittingham, who found that by using titanium disulfide as a cathode in a lithium battery, impressive capacitance characteristics of the battery can be obtained. The only, but very serious disadvantage of such a design was that such a battery was explosive.
In 10 years John Goodenough found a replacement for titanium disulfide-empirically, he proved that cobalt oxide works even better in contact with the lithium anode.
In turn, Akira Yoshino modified the design of the battery, making it resistant to hundreds of consecutive charge-discharge cycles, after which lithium-ion batteries became suitable for commercial use.
The Nobel prize in chemistry for 2019 was eventually given to all three scientists who at different times worked to create batteries that very quickly revolutionized our society by making it wireless.
