ANN ARBOR, Mich. - May 4, 2016 (Investorideas.com renewable energy stocks newswire) For anyone (i.e. everyone) who's ever panicked when their mobile device chirped, "low battery," the future could be far less stressful, thanks to the advanced battery research of scientists at the Toyota Research Institute of North America (TRINA). A new breakthrough involving magnesium batteries may soon open the doors for smaller, longer-lasting batteries for everything from cars to cell phones.
What's the Big Deal with Magnesium?
Magnesium metal has long been theorized as a much safer and more energy-dense alternative to current lithium battery technology. Lithium metal, in its natural state, is unstable and can ignite when exposed to air. In order to make lithium metal safe for batteries, ions are taken from the lithium metal and embedded into graphite rods, which are then used in batteries. That lack of actual metal, however, limits the amount of power a battery can store. Magnesium, on the other hand, is a very stable metal with the potential to store much more energy. But until now, research on magnesium-based batteries was limited because a magnesium-friendly electrolyte did not exist.
Close Collaboration Leads to Discovery
Enter Toyota principal scientist and chemical engineer Rana Mohtadi. Mohtadi was researching hydrogen storage materials and their application to fuel cell technology; upon hearing her fellow researchers discussing the challenges of developing an electrolyte for a practical magnesium battery, Mohtadi realized her hydrogen storage material might just solve the longstanding problem. With further experimentation and the help of fellow researchers, her theory proved correct.
"We were able to take a material that was only used in hydrogen storage and we made it practical and very competitive for magnesium battery chemistry," said Mohtadi. "It was exciting."
Just as exciting as the discovery itself is how Toyota's culture of diversity and collaboration played a key role.
"The results really speak to the strength in our group," said Energy Storage Group Manager Paul Fanson. "We try to put people from diverse backgrounds and diverse technologies together and allow them to collaborate. This is a great example of that working very successfully."
Don't Toss Your LiPo Just Yet
While it's easy to get caught up in the potential of a dramatically improved battery, it could take 20 years of research and development before magnesium batteries reach the consumer market. To help move the process along, Toyota's scientists aren't keeping their discovery to themselves. Fellow researcher Oscar Tutusaus, who collaborated with Mohtadi on the discovery, said, "We want to make this electrolyte a standard for magnesium batteries… and we want other researchers to develop it further so these batteries can see the light of day."
A paper detailing their discovery entitled, "An Efficient Halogen-Free Electrolyte for Use in Rechargeable Magnesium Batteries," was recently published in Angewandte Chemie International Edition (Vol. 54, Issue 27).
Toyota (NYSE:TM), the world's top automaker and creator of the Prius and the Mirai fuel cell vehicle, is committed to building vehicles for the way people live through our Toyota, Lexus and Scion brands. Over the past 50 years, we've built more than 30 million cars and trucks in North America, where we operate 14 manufacturing plants (10 in the U.S.) and directly employ more than 44,000 people (more than 34,000 in the U.S.). Our 1,800 North American dealerships (1,500 in the U.S.) sold more than 2.8 million cars and trucks (nearly 2.5 million in the U.S.) in 2015 – and about 80 percent of all Toyota vehicles sold over the past 20 years are still on the road today.
Toyota partners with philanthropic organizations across the country, with a focus on education, safety and the environment. As part of this commitment, we share the company's extensive know-how garnered from building great cars and trucks to help community organizations and other nonprofits expand their ability to do good.
