Lithium-ion and other advanced battery chemistries have shown promise over the last decade for driving the world’s clean energy strategy with hybrid/electric vehicles (xEVs), grid storage, and other enabling technologies. Of late though, batteries seem to be in the news more for the wrong reasons, spanning issues such as reliability, range anxiety in electric cars, causing large fleets of aerospace vehicles to be grounded/retrofitted with safety protections, and the occasional fiery field failure. Or, if those issues are somehow avoided, then for simply being too expensive and contributing to weak xEV sales.
A key reason for these issues has been the challenge to probe parameters that directly reflect key physical properties related to the degradation and failure of fielded batteries. … read more
