Abstract

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 Ψ 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 <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 <1.2, or are present in at least 40 vol % of the composite material for the polydispersity index of >1.2.
