Building a Better Battery: New Tech Could Make Electric Cars Cheaper

24M, a startup from the cofounder of A123 Systems, just tucked $16 million in financing under its belt to pursue cost-cutting new battery technologies.

The brain behind the batteries used in everything from New York City transit busses to an electric motorcycle that does 0 to 60 miles per hour in under one second is up to something new. Ken Chiang, a cofounder of lithium-ion battery mogul A123 Systems, is striking out on his own under a new marquee to build batteries that could be up to 85 percent cheaper than anything available today.

Chiang will remain at A123, and as a professor of materials science at MIT, but pursue the a different technology at his new company, 24M. On Monday, the company announced it had secured $10 million in venture-capital funding and another $6 million from ARPA-E, a branch of the U.S. Department of Energy. A123 Systems will also retain a stake in the startup.

While Chiang has remained intentionally vague about how the new batteries will work, he claims they will combine attributes of rechargeable batteries, fuel cells, and flow batteries. The breakthrough: A traditional lithium-ion battery wastes significant space within it on construction materials – like the separators between the anode and cathode. Chiang’s new design will eliminate the need for them, potentially increasing energy density and decreasing manufacturing costs.

The cost of traditional lithium-ion batteries accounts for much of the expensive involved with producing hybrid and fully electric vehicles. A replacement battery pack for the Prius costs over $2,000, and early GM estimates put the price of the Chevy Volt’s battery pack as high as $10,000.

But don’t expect a half-price version of the Volt powered by new batteries any time soon. According to MIT’s TechnologyReview, Chiang hopes to have the first demonstrations of his batteries ready within five years.

  1. Sunny Youn at 4:05am 5th May 2011 MIT has done a lot of work on battery technology... heard the VP of Marketing from A123 speak at the NY Academy of Sciences recently and they're working closely with auto manufacturers in Michigan...but competition from China & Korea in battery technology is also heating up... the challenge has been to provide the oomph and zippiness to power a car engine without running out of power...Chiang cracked the code!
  2. Larry D Meador at 1:25pm 2nd November 2010 I have invented a charging system for batteries that will not need to be pluged in to any external electrical outlets.It can be used on all battery products,autos, cell phones etc.A D.C.planet..I need financal help.Email me.
