Jeff Dahn awarded Herzberg Medal for battery research

Jeff Dahn, of Dalhousie University in Halifax, Nova Scotia, won the Herzberg Medal and the million dollars in prize money that comes with the honour.

The award is presented by the Natural Sciences and Engineering Research Council (NSERC). It was announced today along with several other honours.

A member of the Department of Physics and Atmospheric Science at Dal, as it’s affectionately known, Professor Dahn works with a team of about 25 people: undergraduate assistants, graduates and post-doctorates, in a 5,000-square-foot laboratory. It’s a hive of activity with machines humming around the clock.

“I often tell my students our role is not to publish papers in Science and Nature; it’s to do something useful. And I think getting this award really recognizes the fact that we have accomplished some things that have been useful and valuable to society.”

Jeff Dahn is working to increase the capacity of lithium-ion batteries with a team of 25 at Dalhousie University in Halifax.

Lithium-ion batteries are common in every day use in smartphones, laptops and to the increasingly popular electric car. Dahn has had a major role in making these batteries more efficient.

Now Dahn is working with Tesla, the American electric car company, aiming to make a battery that lasts 30 years.

“No matter what electric chemical energy storage technology you pick… they have to last many decades to be viable for our planet,” Dahn told CBC News. “Germany has said that by 2050 they’re going be 100 per cent renewable. Well, how are they going to do it? How are they going to use solar and wind and storage to do it?”

Dahn’s research is centred on “unwanted parasitic reactions,” which reduces battery life.

“Our job is to make them zero,” he said. “And it’s very tough.”

Last year Tesla Motors entered into a five-year partnership with NSERC and Dalhousie University, creating the NSERC/Tesla Canada Industrial Research Chair, headed by Dahn.

It is Dahn’s second chair: he held the NSERC/3M Canada Industrial Research Chair in Materials for Advanced Batteries at the university from 1996 to 2016.

Tesla is at the forefront of grid-energy and electric vehicle research and it is the first time the company has partnered with a university researcher.

It’s the ideal partnership for Professor Dahn. Like Tesla founder and CEO Elon Musk, Dahn sees the need to shift to renewable energy technology.

“At this moment, we’ve been working with Tesla only for six months so far, and none of our research has made it into their products yet, but I’m quite confident that our work will be incorporated in their products going forward, and that’s pretty exciting for us.” Dhan said.

While Dahn won a Governor General’s Award for Innovation in 2016, and is the co-inventor of more than 65 inventions, and helped develop technology to test the lifespan of batteries, he modestly believes he has played a small part in battery research.

“A lot of people ascribe the success of lithium-ion cells way too much to me and my group,” he said. “We’ve made small contributions along the way that have been important, but many, many other labs around the world and companies too have done a lot.”

Netiquette
When you express your personal opinion in an online forum, you must be as courteous as if you were speaking with someone face-to-face. Insults and personal attacks will not be tolerated. To disagree with an opinion, an idea or an event is one thing, but to show disrespect for other people is quite another. Great minds don’t always think alike—and that’s precisely what makes online dialogue so interesting and valuable.

Netiquette is the set of rules of conduct governing how you should behave when communicating via the Internet. Before you post a message to a blog or forum, it’s important to read and understand these rules. Otherwise, you may be banned from posting.

  1. RCInet.ca’s online forums are not anonymous. Users must register, and give their full name and place of residence, which are displayed alongside each of their comments. RCInet.ca reserves the right not to publish comments if there is any doubt as to the identity of their author.
  2. Assuming the identity of another person with intent to mislead or cause harm is a serious infraction that may result in the offender being banned.
  3. RCInet.ca’s online forums are open to everyone, without regard to age, ethnic origin, religion, gender or sexual orientation.
  4. Comments that are defamatory, hateful, racist, xenophobic, sexist, or that disparage an ethnic origin, religious affiliation or age group will not be published.

Any message containing one or more words in all caps (except for initialisms and acronyms) will be rejected, as will any message containing one or more words in bold, italic or underlined characters.
  6. Use of vulgar, obscene or objectionable language is prohibited. Forums are public places and your comments could offend some users. People who use inappropriate language will be banned.
  7. Mutual respect is essential among users. Insulting, threatening or harassing another user is prohibited. You can express your disagreement with an idea without attacking anyone.

The language used in the forums has to be the same as the contents we publish or in one of the two official languages, English or French. The usage of other languages, with the exception of some words, is forbidden. Messages that are off-topic will not be published.
  10. Making repetitive posts disrupts the flow of discussions and will not be tolerated.
