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: LiMMM(PO), 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. Mis selected from Al, Y, Sc or B, wherein at least Al as trivalent cation is present. Independently thereof, Mis selected from Ti, Si or Zr, wherein at least Ti as tetravalent cation is present. Independently thereof, Mis selected from Nb or Ta.

Glass ceramic with ion-conducting residual glass phase and process for the production thereof

A lithium-ion-conducting composite material and process of producing are provided. The composite material includes at least one polymer and lithium-ion-conducting particles. The particles have a sphericity &#x3a8; of at least 0.7. The composite material includes at least 20 vol % of the particles for a polydispersity index PI of the particle size distribution of &#x3c;0.7 or are present in at least 30 vol % of the composite material for the polydispersity index in a range from 0.7 to &#x3c;1.2, or are present in at least 40 vol % of the composite material for the polydispersity index of &#x3e;1.2.
