    Abstract: The disclosure relates to a method for producing a solid-state lithium ion conductor material in which the use of water and/or steam is a medium when the obtained intermediate product is cooled or quenched and, if needed, comminution of the intermediate product and/or carrying out of a cooling process with the production of a powder in one comminution step or in a plurality of comminution steps leads or lead to especially advantageous production products. The subject of the disclosure is also the solid-state lithium ion conductor material that has an ion conductivity of at least 10−5 S/cm at room temperature as well as a water content of

    Abstract: The present disclosure relates to a lithium ion-conducting glass ceramic which comprises a residual glass phase that is also ion-conducting, a process for the production thereof as well as its use in a battery. The glass ceramic according to the present disclosure comprises a main crystal phase which is isostructural to the NaSICon crystal phase, wherein the composition can be described with the following formula: Li1+x−yMy5+Mx3+M2−x−y4+(PO4)3, wherein x is greater than 0 and at most 1, as well as greater than y. Y may take values of between 0 and 1. Here, the following boundary condition has to be fulfilled: (1+x−y)>1. Here, M represents a cation with the valence of +3, +4 or +5. M3+ is selected from Al, Y, Sc or B, wherein at least Al as trivalent cation is present. Independently thereof, M4+ is selected from Ti, Si or Zr, wherein at least Ti as tetravalent cation is present. Independently thereof, M5+ is selected from Nb, Ta or La.

    Abstract: The disclosure relates to an aluminum-doped lithium ion conductor based on a garnet structure comprising lanthanum, in particular an aluminum-doped lithium lanthanum zirconate (LLZO), in which the latter is co-doped with at least one trivalent M3+ ion on the lanthanum site, and in which the trivalent M3+ ion has an ionic radius that is smaller than that of La3+, and a higher lithium content is present in comparison to a stoichiometric garnet structure, with the provision that if M3+ is yttrium, a further trivalent M3+ ion, which is different than Y3+ and has an ionic radius that is smaller than that of La3+, is co-doped on the lanthanum site. A co-doping strategy is carried out, in which a doping on the lanthanum site with ions of the same valence, but smaller diameter brings about the change in the lattice geometry to the cubic modification. This leads to a stabilization of the cubic crystal modification that is present also with superstoichiometric quantities of lithium.
