LOW-COST MULTI-CATIONIC LI-GARNET AS A SOLID-STATE IONIC CONDUCTOR FOR LITHIUM BATTERIES
A lithium garnet material has the formula Li7-wLa3-x(Ax1Bx2Cx3)Zr2-y(Cy1Dy2Ey3)O12, where -0.2 ≤ w ≤ 0.2, A is one or a combination of Na+ and K+, B is one or a combination of two or more of Mg2+, Ca2+, Sr2+, and Ba2+, and C is one or a combination of two or more of Y3+, Sc3+, and Ce3+ on the La3+ site, and D is one or a combination of two or more of Si4+, Sn4+, Ti4+, and Ce4+ and E is one or a combination of two or more of Sb5+, Bi5+, Ta5+, and Nb5+ on the Zr4+ site, 0 < x < 2, 0 < y < 2, and x1 + x2 + x3 = x and y1 + y2 + y3 = y either satisfy a charge balance mechanism with their respective doping site or satisfy any combination that maintains the charge neutrality of the material.
