<p>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 MI 1+x+z-deltaMIII xMIVa yMIVb 2-x-yMV zP3-zO12 and MI 1+x+4z-deltaMIII xMIVa yMIVb 2-x-y-zP3O12, wherein MI comprises Li, Na, or mixtures thereof; 0.05<x<0.5, 0.05<y<2, 0< z<3, and 0<delta<0.5; Mm comprises A1, Hf, Sc, Y, La, or mixtures thereof; MIVa comprises Zr, Ge, Sn, or mixtures thereof; MIVb comprises Ti; and MV comprises 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.</p> |
