Publication number: 20210344039Abstract: 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.Type: ApplicationFiled: April 29, 2021Publication date: November 4, 2021Applicant: SCHOTT AGInventors: Sebastian Leukel, Meike Schneider, Andreas Roters, Jörg Schumacher, Wolfgang Schmidbauer, Bernd Rüdinger
