The present invention relates to glasses having a composition made up of base glasses. The glasses have a good chemical toughenability in combination with an advantageous coefficient of thermal expansion. Owing to their composition and the production process, the homogeneity of the properties of the glasses at their surface is high compared to the bulk glass. Furthermore, the fragility of the glasses is low, so that they can be processed to produce very thin glass articles.

Glasses having improved ion exchangeability and thermal expansion

An additive for electrochemical energy storages is disclosed, wherein the additive contains at least one silicon- and alkaline earth metal-containing compound V1 which in contact with a fluorine-containing compound V2 in the energy storage forms at least one compound V3 selected from the group consisting of silicon- and fluorine-containing, lithium-free compounds V3a, alkaline earth metal- and fluorine-containing, lithium-free compounds V3b, silicon-, alkaline earth metal- and fluorine-containing, lithium-free compounds V3c and combinations thereof. Also disclosed is an electrochemical energy storage containing the additive.
