A lithium ion-conducting compound, having a garnet-like crystal structure, and having the general formula: Li[AA'A&#x2033;][BB&#x2032;B&#x2033;][C&#x2032;C&#x2033;]O, where A, A&#x2032;, A&#x2033; stand for a dodecahedral position of the crystal structure, where A stands for La, Y, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm and/or Yb, A&#x2032; stands for Ca, Sr and/or Ba, A&#x2033; stands for Na and/or K, 0&#x3c;a&#x2032;&#x3c;2 and 0&#x3c;a&#x2033;&#x3c;1, where B, B&#x2032;, B&#x2033; stand for an octahedral position of the crystal structure, where B stands for Zr, Hf and/or Sn, B&#x2032; stands for Ta, Nb, Sb and/or Bi, B&#x2033; stands for at least one element selected from the group including Te, W and Mo, 0&#x3c;b&#x2032;&#x3c;2 and 0&#x3c;b&#x2033;&#x3c;2, where C and C&#x2033; stand for a tetrahedral position of the crystal structure, where C stands for Al and Ga, C&#x2033; stands for Si and/or Ge, 0&#x3c;c&#x2032;&#x3c;0.5 and 0&#x3c;c&#x2033;&#x3c;0.4, and where n=7+a&#x2032;+2&#xb7;a&#x2033;&#x2212;b&#x2032;&#x2212;2&#xb7;b&#x2033;&#x2212;3&#xb7;c&#x2032;&#x2212;4&#xb7;c&#x2033; and 5.5&#x3c;n&#x3c;6.875.

Lithium ion-conducting garnet-like compounds

An all-solid-state cell, which includes a lithium-containing anode, a cathode and a lithium ion-conducting solid-state electrolyte separator situated between the anode and the cathode. To improve the safety and cycle stability of the cell, the cathode includes a composite material including at least one lithium titanate and at least one lithium ion-conducting solid-state electrolyte. Furthermore, the invention relates to a corresponding all-solid-state battery and a mobile or stationary system equipped with it.
