Researchers at the University of Colorado Boulder have developed a solid-state battery technology which should reduce the size, weight and complexity for EV applications.
The University has formed a commercial agreement with Solid Power to develop and commercialise a rechargeable battery with funding from the U.S. Department of Energy’s Advanced Research Projects Agency, which was awarded specifically to develop the technology for EVs.
The full story on phys.org explains how the technology works and how it should result in smaller, lighter batteries…
“Today’s lithium-ion batteries require a bulky amount of devices to protect and cool the batteries… …Lee and Stoldt solved the safety concerns around using lithium metal by eliminating the liquid electrolyte. Instead, the pair built an entirely solid-state battery that uses a ceramic electrolyte to separate the lithium metal anode from the cathode. Because the solid-state battery is far safer, it requires less protective packaging, which in turn could reduce the weight of the battery system in electric vehicles and help extend their range”
“The real innovation is an all-solid composite cathode that is based upon an iron-sulfur chemistry that we developed at CU… …This new, low-cost chemistry has a capacity that’s nearly 10 times greater than state-of-the-art cathodes.”
Last year, Lee and Stoldt partnered with Investor Douglas Campbell to create Solid Power.
