Akira Yoshino

Akira Yoshino ( Japanese 吉野 彰 ; born January 30, 1948 in Suita , Osaka Prefecture ) is a Japanese engineer . He is best known for the market-ready development of lithium-ion batteries . In 2019 he was awarded the Nobel Prize in Chemistry.

Life

Yoshino acquired in 1970 at the Kyoto University a bachelor and in 1972 a Master in Engineering Sciences , 2005 at the University of Osaka a Dr.-Ing. From 1972 he worked for Asahi Kasei , from 1994 to 1997 for A&T Battery , a joint venture between Asahi Kasei and Toshiba , and from 1997 again for Asahi Kasei. Here he is (as of 2018) General Manager of the Yoshino Laboratory and President of the Lithium Ion Battery Technology and Evaluation Center (LIBTEC). Yoshino has also held a professorship at Meijō University since 2017 .

Act

Yoshino began developing rechargeable batteries in 1981, initially based on lithium cobalt (III) oxide ( lithium cobalt dioxide accumulator ), a discovery by John B. Goodenough . In 1983 Yoshino was able to present a first prototype that used polyacetylene as an anode , but later replaced polyacetylene with carbon compounds (patented 1985). Batteries of this type were commercially available from 1991 ( Sony ) and 1992 (A&T Battery). Further improvements that can be traced back to Yoshino are the use of aluminum foils as a separator , winding as a construction principle, and various safety devices and charging methods.

In 2019, Yoshino was awarded the Nobel Prize in Chemistry for developing lithium-ion batteries. At the announcement, the Nobel Prize Committee emphasized that they have laid the foundation for a wireless, non-fossil fuel society. Yoshino responded to the award with the words: “ Climate change is a serious threat. Lithium-ion batteries can make a contribution to a sustainable future. ”He points out the importance of recyclable batteries.
