ENHANCED-SAFETY GALVANIC ELEMENT

摘要

A separator for a galvanic element, more particularly a lithium ion cell, includes at least one positive electrode and at least one negative electrode that are configured to be separated by a separator. The separator includes a substrate composed of at least one high-temperature-resistant, fiber-forming polymer that has a melting point above 200° C. The substrate also includes at least one further polymer that has a lower melting point than the high-temperature-resistant polymer of the substrate and that connects the fibers of the high-temperature-resistant polymer.

1. A separator for a galvanic element including at least one positive electrode and one negative electrode to be separated by the separator, comprising:
a substrate including (i) at least one high-temperature-resistant, fiber-forming polymer having a melting point above 200° C. and (ii) at least one further polymer having a lower melting point than the high-temperature-resistant polymer of the substrate and being configured to connect the fibers of the high-temperature-resistant polymer.
