I have always been interested in the natural world. And when I was in elementary school one of my teachers suggested that I read The Chemical History of a Candleby Michael Faraday. And that stirred up a lot of questions for me. I hadn’t been interested in chemistry until then. That’s how it all started. I then went on to study quantum organic chemi...
In the early 1970s, I joined the Exploratory Research Team at Asahi Kasei Corporation to explore new general-purpose materials. The projects I worked on initially didn’t work out, so I was looking for a new research focus. At the time, there was great interest in polyacetylene, a fascinating electro-conductive polymer that had been predicted by Dr....
All went well for a while. The prototype was one-third lighter than a standard nickel-cadmium battery, which was good, but we only achieved a slight weight reduction and were unable to reduce the size of the battery. This put the whole venture into question because miniaturization was a priority for the electronics industry. The problem was the sma...
As we were not battery specialists at Asahi Kasei, in-house discussions about what industry needed led nowhere. And of course, you can’t just go to a battery manufacturer and expect them to share their confidential early stage research with you. But I met a former classmate of Asahi Kasei’s executive officer who was a battery company executive and ...
Lithium-ion batteries have made today’s mobile IT society a reality. And in the future, they will play a central role in building a sustainable society. A rechargeable battery with the ability to store electricity is a key device for solving environmental problems. This became more widely recognized around 2010, when electric vehicles (EVs) came on...
The fundamental spirit of patent law is to encourage technological development for the benefit of all. In return for acquiring exclusive patent rights, you reveal [disclose] a new technology to the world, and thereby support its broad dissemination. That is what happened with lithium-ion batteries. Asahi Kasei was good at developing battery technol...
In today’s globalized world, it has become difficult to exercise exclusive patent rights on patents. Even if you tell people not to imitate, they do! Moreover, patent rights are time limited so it is very difficult to take advantage of their economic value through licensing alone. I think it is important to think about other ways to get a payback o...
Researchers from industry differ from academic researchers in the way they announce their results. Academic researchers publish their work, whereas the work of industrial researchers is embedded in patent literature, which is hard to understand and, until recently, was not highly considered in academic circles. However, the Nobel Committee’s citati...
The time frame for taking on new challenges is limited to a certain age; around 35. That’s when successive generations of Nobel Prize winners started their research. I started basic research on lithium-ion batteries at 33. At that age, you understand the workings of a company and of society and have the confidence and authority to start a new ventu...
Akira Yoshino. The Nobel Prize in Chemistry 2019. Born: 30 January 1948, Suita, Japan. Affiliation at the time of the award: Asahi Kasei Corporation, Tokyo, Japan; Meijo University, Nagoya, Japan. Prize motivation: “for the development of lithium-ion batteries”. Prize share: 1/3.
Dr. Yazami used a solid electrolyte, this experiment provided the scientific basis for the use of graphite as negative electrode material—as is the mainstream in LIBs today. In the early 1980s, Dr. Yoshino conceived the idea of a new secondary battery using LiCoO 2 as positive electrode and polyacetylene as negative electrode.

Jan 13, 2016 · Dr. Yoshino filed the first basic patent for the lithium-ion battery in 1985. Working for Asahi Kasei Corporation in Japan, he incorporated lithium cobalt for the positive electrode and a carbonaceous material for the negative electrode. He developed an aluminum foil current collector, and his functional separator and positive temperature ...
