Some materials show ionic conduction, even though they are solids, which are called solid electrolytes. Use of solid electrolytes makes batteries to have long life and, especially in the case of lithium batteries, completely overcome their safety issues originated from their combustible organic electrolytes. Studies in All Solid-State Battery Group are aiming at the development of such solid-state batteries.
