The company is a spin-out from the University of Colorado Boulder and has been developing solid-state rechargeable batteries since 2012. BMW is partnering with Solid Power to bring its battery technology to electric vehicles. "Since the company's inception, the Solid Power team has worked to develop and scale a competitive solid-state battery paying special attention to safety, performance and cost," Doug Campbell, founder and CEO of Solid Power, said in a statement. "Collaborating with BMW is further validation that solid-state battery innovations will continue to improve electric vehicles."
