Beschreibung
Zusammenfassung:A galvanic element has a positive electrode, a negative electrode and a separator lying in between, wherein the separator consists at least partially of a polymer of which the melting and/or softening temperature is >200° C. A multi-layer separator for galvanic elements, in particular for lithium-ion batteries, includes at least one layer of the polymer with a melting and/or softening temperature >200° C.
