The Department of Energy's Battery500 consortium announced its list of 15 new projects promising battery technology advancements in July, and who also received more than $5.7 million in seed funding.

The goal of the Battery500 project is to jump-start technologies that could ultimately lead to 500 Wh/kg+ energy density cells - a level seen as part of the "Holy Grail" for widespread EV adoption.

During the next 18-months (phase 1) awardees will show proof of thier technologies, and then will be down-selected for further financing.

"The new projects are the first to be funded through the consortium, which is led by DOE's Pacific Northwest National Laboratory and involves multiple partners at universities and other national labs. The new seedling projects were announced July 12 as part of a larger unveiling of a total of $19.4 million in new DOE funding for vehicle technologies research.

The new consortium projects are called seedling projects because they involve new, potentially risky battery technologies that could pay off big and grow into significant energy storage solutions. The most promising of the new projects will be competitively down-selected after 18 months.

Battery500 seeks to develop lithium-metal batteries that have more than double the specific energy found in batteries that power today's electric cars. Specific energy measures the amount of energy packed into a battery based on its weight.

Batteries with higher specific energies will allow electric vehicles (EVs) to drive farther on a single charge, as well as weigh and cost less. The consortium aims to build a battery cell with a specific energy of 500 watt-hours per kilogram, compared to the 170-200 watt-hours per kilogram in today's typical EV battery."

"The Battery500 project is focused on three keystone projects:

  • A high nickel content cathode with a Li-metal anode;
  • Sulfur cathode and Li-metal anode; and
  • Innovative electrode and cell design."
