I was beaming with delight when I read that John Goodenough, Stanley Wittingham and Akira Yoshino received the 2019 Nobel Prize in Chemistry for the “development of lithium-ion batteries.”

Wittingham’s initial work on batteries dates back to the 1970s while at Exxon. Goodenough’s seminal work on LCO cathodes at Oxford was published in 1980. Yoshino’s contributions on the graphite anode came in 1980s at Asahi Kasei in Japan. Sony converted their ideas into the first commercial lithium-ion battery product in 1991.
