Sandia testing method yields pathway to better, longer-lasting solid-state batteries

Green Car Congress

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. Solid-state batteries employ solid electrolytes instead of electrochemical gels and liquids and generally power small electronics.
