SOLID CERAMIC ELECTROLYTES

摘要

A solid ceramic electrolyte may include an ion-conducting ceramic and at least one grain growth inhibitor. The ion-conducting ceramic may be a lithium metal phosphate or a derivative thereof. The grain growth inhibitor may be magnesia, titania, or both. The solid ceramic electrolyte may have an average grain size of less than about 2 microns. The grain growth inhibitor may be between about 0.5 mol.% to about 10 mol.% of the solid ceramic electrolyte.
