Solid Power in the US has been granted funding from the Department of Energy (DOE) ARPA-E group to continue its development of nickel- and cobalt-free solid-state battery cells.
Solid Power expects to receive up to $5.6 million to develop battery cells containing a lithium metal anode and sulfur composite cathode to enable improved energy and charging performance.

“Replacing costly nickel and cobalt in the cathode with sulfur could lead to a lower cost EV battery with improved energy and fast-charging capabilities,” said David Jansen, Interim CEO, President and Chair of Solid Power. “I’d like to thank the Solid Power development team for their outstanding work and the DOE for their continued confidence in our company’s value proposition.”
The DOE recently announced $42m for 12 projects to strengthen the domestic supply chain for advanced batteries for electric vehicles (EVs). The Electric Vehicles for American Low-Carbon Living (EVs4ALL) programme also projects to achieve a charge rate equivalent to 5-15 minutes to restore 80% of cell capacity and to reduce low-temperature battery performance losses by at least 50%.
This is also looking at projects to boost the lifetime of battery cells so that they keep a minimum of 90% capacity after the battery has delivered 200,000 miles of range.
Solid Power recently signed a deal for BMW to set up its own pilot line in Germany to make solid state battery cells.
