Aluminium-doped lithium ion guide based on a granite structure

摘要

The invention concerns an aluminium-doped lithium ion conductor based on a granite structure, comprising lanthane, in particular an aluminium-doped lithium lanthane zirconium (LLZO),where this/this is coded with at least one triple Ion M3+ on the Lanthan site, the triple Ion M3+ having an Ion radius smaller than that of La3+,and a higher lithium content compared to a stoichiometric granate structure, provided that if M3+ Yttrium is another three-value Ion M3+,which is different from Y3+ and has an ion radius smaller than that of La3+,on the Lanthanplatz is coded.A coding strategy is implemented whereby a dose on the Lanthan site with ions of equal value, but smaller diameter, changes the grid geometry to cubic modification.This results in a stabilization of the cubic crystal modification, which is also present in excess of the isometric quantities of lithium.
