Abstract: A cover glass made of a glass ceramic that is silica based and has a main crystal phase of high quartz solid solution or keatite solid solution is provided. The cover glass has a stress profile with at least one inflection point at a depth of the cover glass of more than 10 μm, a thickness from 0.1 mm to 2 mm, and a chemical tempering structure with a surface compressive stress of at least 250 MPa and at most 1500 MPa. A process for producing the cover glass is provided that includes producing a silica based green glass, hot shaping the silica based green glass, thermally treating the silica based green glass with a nucleation step and a ceramization step, and performing an ion exchange at an exchange bath temperature for a duration of time in an exchange bath.

Abstract: A lithium-ion-conducting composite material is provided that includes at least one polymer and lithium-ion-conducting particles. The interfacial resistance for the lithium-ion conductivity between the polymer and the particles is reduced as a result of a surface modification of the particles and therefore the lithium-ion conductivity is greater than for a comparable composite material wherein the interfacial resistance between the polymer and the particles is not reduced.
