John B. Goodenough is credited for the identification and initial development of the first lithium-ion (Li-ion) batteries. He is a professor of Mechanical, Materials Science, and Electrical Engineering at the University of Texas. Goodenough worked as a meteorologist in the US army during World War II. Along with many other scientific awards he received the Nobel Prize in Chemistry (2019) alongside M. Stanley Whittingham and Akira Yoshino. Goodenough was 97 years old, when he became the oldest Nobel laureate in history.
Lithium ion batteries changed the way the world stores energy. They provide high levels of charge than other battery technologies, and they have a higher voltage.
