Chances are—you’re currently reading this article on your mobile phone or your laptop—and you have M. Stanley Whittingham, 78, Ph.D., to thank for that.

Whittingham is not only the key figure in the history of the development of lithium-ion batteries, he’s also the founding father of rechargeable lithium-ion batteries. These lightweight yet powerful and rechargeable batteries are used in everything today—from smart phones to laptops and even electric vehicles.

It is no wonder that the British transplant is one of three scientists who was awarded the 2019 Nobel Prize in Chemistry for the development of lithium-ion batteries. (The other two scientists who developed and further evolved lithium-ion batteries after Whittingham include John B. Goodenough, with whom Whittingham co-wrote a book, and Akira Yoshino from Japan).

Whittingham was the first of the three laureates to tackle fossil-fuel-free energy back in the 1970s during the oil crisis, while being employed at Exxon. That’s when he worked on developing methods that could lead to fossil-fuel-free energy technologies. He started researching superconductors and discovered an exceptionally energy-rich material that he used to create an innovative cathode in a lithium-ion battery. This was made from titanium disulfide—which had never been used in batteries before and at an atomic level allows lithium ions to move between its layers. This resulted in the first functional rechargeable lithium-ion battery.

After 16 years at Exxon, Whittingham moved on to academia and has worked as professor of Chemistry and Materials Science & Engineering at Binghamton University in New York since 1988. He’s married to a fellow professor of Spanish, Georgina, has two children and four grandchildren.

Whittingham holds 16 patents, co-wrote five books, contributed to more than 200 publications and has won seven awards for his work, including the esteemed Nobel Prize. Nevertheless, the prolific scientist found time to sit down with BASF for an interview.

The Nobel laureate is well acquainted with the chemical company. He provided consulting services to BASF’s Catalysts division in Iselin, NJ on lithium-ion batteries and battery materials back in 2006. He also took part in The Science Award Electrochemistry award ceremony last year in Wolfsburg, Germany—a joint initiative of Volkswagen and BASF aimed at young scientists of excellence in electrochemistry. Most recently, in an opportunity to honor the Nobel laureate, BASF’s Battery Materials site in Beachwood, OH named one of its conference rooms after the British professor.

BASF: Congratulations on your prestigious award. You are the key figure in the history of the development of lithium-ion batteries, as well as the founding father of rechargeable lithium-ion batteries. Could you take us to the very beginning—how did you get interested in chemistry and rechargeable batteries?

M. Stanley Whittingham: I got interested in chemistry through two, what you would call, high school teachers. I was at Stamford School in England. I had a good chemistry teacher, a very good physics teacher, and they got me totally committed to chemistry and physics. Then I went to Oxford and studied chemistry. Afterwards, I went to Stanford—at that time Ford Motor Co. had just made the discovery of a material that conducted sodium ions almost as fast as liquid solutions. We said “Hey, maybe we can do something at room temperature.” All the lithium and sodium batteries at that time were about 300, 400-degrees centigrade. When I moved on to the workforce, there was interest in superconductors using intercalation reactions to change the superconducting transition temperature, and I was making some of these from just aqueous solutions. There was a lot of heat evolved, so I said “Hey, we can harness the heat,” so that’s when we started getting into batteries. My company just started up a corporate lab so they could become an energy company, not just a petroleum and chemicals company. We were told to work on anything energy-related, provided it wasn’t petroleum and chemicals.

Clearly, sustainability came into focus much later in our society, do you think you were ahead of your time with fossil-fuel-free energy technology?

Yes and no. In the end, we were ahead of our time in my work, the oil industry thought oil production was going to peak about the year 2000. They were already planning on having to diversify beyond just oil. My company was interested in batteries at the time, fuel cells and solar cells. It did all the nuclear reprocessing for the U.S.

Initially used in electronics—I’ll call them toys or phones, computers, etcetera—batteries showed enablers how to have a much cleaner environment, get away from dirty diesel engines and to go to more hybrid or even all-electric. Batteries enable wind and solar farms as well, and they are beginning to dominate in that field. I think lithium ions will help us maybe get the climate change under control a bit more.

Could you share some of the challenges of working with efficient batteries? Did they initially catch fire?

No, we didn’t have too many issues. Initially, we did everything on the lab bench. We were bought glove boxes. Then the engineering team got a dry room. There were no fire issues with batteries, whilst they were operating. The issues arose only when the batteries were pulled apart for postmortems. In the dry room, they’d sometimes catch fire because they had finely divided lithium in them—that was the big issue. Otherwise, we didn’t have any fire issues in the lab.

How did you end up collaborating with Dr. John Goodenough—one of the other 2019 Chemistry laureates for battery materials?

I met him in the early 1980s at Oxford once when my wife and I went over there—we all had tea together at Randolph Hotel. We published our work on titanium disulfide. John was looking at the magnetic properties of the lithium cobalt oxide. He added two and two together and said: “Lithium cobalt oxide is the same structure as lithium titanium disulfide—I’m going to try and use it as a battery.” And that’s how he got into cobalt oxide batteries.

An interesting side to all this—I was English and made my invention in the U.S. While John was an American and made his invention in England. But there was no direct interaction between our group and his group at the time, just as there was no direct interaction between our Exxon group and the Japanese group (under Akira Yoshino).

Afterwards, I’ve worked with John on and off. We both ran a big symposium for the American Chemical Society in New York City. We have a book that came out of that collaboration. We are now partners in the large Battery500 consortium, so we’re probably working closer together today than we ever have in the past. My work on battery materials was in the 1970s, John’s was really in the 1980s and shortly after our Japanese colleague Akira developed the anode (1985). I came up with the intercalation concept—the idea. John came up with the cathode to make it economically viable; then Akira came up with the anode and built a battery in which Sony took an interest—since that was the company that licensed the battery at the end.

You’ve obviously accomplished some amazing goals. What word of advice would you give to young chemists or STEM graduates entering the workforce?

I keep telling graduate students—you have to do what excites you. Don’t do it for the money; and be willing to take risks and make some mistakes. If you don’t take risks, you won’t make any major breakthroughs. But if you take risks—you can get some things wrong. You’ve got to take those risks and plow ahead and believe in what you’re doing.

You married a fellow professor. Does your wife share your interest in lithium-ion batteries?

Yes and no. She says they’re double-edged swords. She teaches languages and literature. She says the students are always trying to look at their phones instead of listening to her. She’s excited about it though (lithium ions).

After winning the most prestigious award in Chemistry, what’s next for you? Is there something you look forward to working on now?

First, I have to get both feet on the ground. I’m still working on Battery500, they’re still doing a lot of battery research in Binghamton. The state—within the last three years—has put several million dollars into my group.  We have our own dry room and a small pouch cell prototype manufacturing line. I’ve got lots of excited graduate students and postdocs. As long as my health holds up, I will keep going—and my doctor tells me not to retire.

SUNY Board of Trustee chair Merryl H. Tisch, Chancellor Kristina M. Johnson and Binghamton University President Harvey Stenger were a few of the many who congratulated  Distinguished Professor of Chemistry and Materials Science M. Stanley Whittingham for his recent 2019 Nobel Prize win in chemistry at a ceremony held in his honor at the Anderson Center for the Performing Arts, Friday, October 18, 2019.
