Cheaper, more powerful electric car batteries are on the horizon

August 09, 2016

BINGHAMTON, NY - A more powerful and efficient electric car could be here sooner than you think, thanks to a new consortium that includes Binghamton University, State University of New York.

The White House recently announced the creation of the Battery500 Consortium, a multidisciplinary group led by the U.S. Department of Energy (DOE) Pacific Northwest National Laboratory (PNNL) and working to reduce the cost of vehicle battery technologies. The Battery500 Consortium will receive an award of up to $10 million per year for five years to drive progress on DOE's goal of reducing the cost of vehicle battery technologies.

The group aims to triple the specific energy relative to today's battery technology while achieving 1,000 electric vehicles cycles. This will result in a significantly smaller, lighter weight, less expensive battery pack (below $100/kWh) and more affordable electric vehicles. M. Stanley Whittingham, distinguished professor of chemistry at Binghamton University, will lead his Energy Storage team in the charge.

"We hope to extract as much energy as possible while, at the same time, producing a battery that is smaller and cheaper to produce," said Whittingham. "This consortium includes some of the brightest minds in the field, and I look forward to working with them to create lithium batteries that will power future electric vehicles more affordably."

The team will design new electrode and cell architectures, pairing lithium metal as the negative electrode with two different materials for the battery's positive electrode. In this redesigned battery, the prevention of unwanted side reactions will significantly improve battery performance.

Other Battery500 Consortium members include:

  • Pacific Northwest National Laboratory
  • Brookhaven National Laboratory
  • Idaho National Laboratory
  • SLAC National Accelerator Laboratory
  • Stanford University
  • University of California, San Diego
  • University of Texas at Austin
  • University of Washington
  • IBM (advisory board member)
  • Tesla Motors, Inc. (advisory board member)

The consortium also welcomes ideas from others, recognizing that diversity in experience and opinions often results in better solutions. The team will set aside 20 percent of its overall budget for "seedling projects," or work based on proposals from throughout the battery research community.

The Flag and the Fury
How do you actually make change in the world? For 126 years, Mississippi has had the Confederate battle flag on their state flag, and they were the last state in the nation where that emblem remained "officially" flying.  A few days ago, that flag came down. A few days before that, it coming down would have seemed impossible. We dive into the story behind this de-flagging: a journey involving a clash of histories, designs, families, and even cheerleading. This show is a collaboration with OSM Audio. Kiese Laymon's memoir Heavy is here. And the Hospitality Flag webpage is here.
