10 Start-ups To Watch

Automakers have their pedals to the metal when it comes to developing battery-powered cars, but electrochemists still have their work cut out to deliver the battery performance and safety that large-scale adoption requires. Current lithium-ion batteries typically operate with a lithium-ion cathode, graphite anode, and liquid electrolyte. But liquid electrolytes can become dangerously hot and catch fire. A safer solution—and one that could also facilitate greater energy density—is to switch to a solid electrolyte. Solid Power, a spin-off from the University of Colorado, Boulder, claims its lithium-sulfide solid electrolyte can be produced at about the same cost as a liquid electrolyte..
