Using a microscopic method for measuring electrical potential, a team of scientists at Sandia National Laboratories may have discovered how to identify rate-limiting processes in solid-state batteries. The findings are detailed in a paper in American Chemical Society Energy Letters. The performance of solid-state electrochemical systems is intimately tied to the potential and lithium distributions across electrolyte–electrode junctions that give rise to interface impedance.
