ELECTROCHEMICAL ENERGY ACCUMULATOR AND USE OF A GLASS-BASED MATERIAL FOR PRODUCING A SEPARATOR FOR SAID ACCUMULATOR

摘要

The invention relates to a material based on glass which is suitable for producing a separator for an electrochemical energy accumulator, in particular for a lithium-ion accumulator. Said glass-based material contains the following components (in wt. % based on oxide): SiO2 + F + P2O5 20 - 95; Al2O3 0,5 - 30, wherein the density is less than 3.7 g/cm3.
