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 <1.0 wt %. The disclosure further relates to the use of the solid-state lithium ion conductor material in the form of a powder in batteries or rechargeable batteries, preferably lithium batteries or rechargeable lithium batteries, in particular, separators, cathodes, anodes, or solid-state electrolytes.
