Abstract
Described herein are devices and methods for generating new, lower-cost chloride solid electrolytes useful for lithium ion batteries. The devices replace higher cost, difficult to acquire elements such as Sc with less expensive, readily available elements such as Mg and Zr to form a highly conductive spinel structure. These materials may have a high ionic conductivity on the order of 0.23 mS/cm.
