Abstract
Lithium-ion-conducting ceramic materials are disclosed having characteristics of high lithium-ion conductivity at low temperatures, good current efficiency, and stability in water and corrosive media under static and electrochemical conditions. Some general formulas for the lithium-ion-conducting materials include MMMMMPOand MMMMPO, wherein Mcomprises Li, Na, or mixtures thereof; 0.05<x<0.5, 0.05<y<2, 0≦z<3, and 0≦δ<0.5; Mcomprises Al, Hf, Sc, Y, La, or mixtures thereof; Mcomprises Zr, Ge, Sn, or mixtures thereof; Mcomprises Ti; and Mcomprises Si, Ge, Sn, or mixtures thereof. In some cases, the lithium-ion conducting materials are formed through a process in which the materials' powdered precursors are milled after being calcined and before being sintered. The milling process may include using milling media of multiple sizes.
