Abstract

The present invention pertains to a membrane for an electrochemical device, to a process for manufacturing said membrane and to use of said membrane in a process for manufacturing an electrochemical device.

Description

[0001] This application claims priority from European Application No. EP 16305722.7 filed on June 14, 2016, the entire content of which is hereby incorporated by reference for all purposes. technical field [0002] The invention relates to a membrane for an electrochemical device, a method for producing the membrane and the use of the membrane in a method for producing an electrochemical device. Background technique [0003] Fluoropolymers and particularly vinylidene fluoride polymers are used in a wide variety of applications including electrochemical applications. [0004] For example, due to their chemical resistance and thermal aging resistance, fluoropolymers are advantageously used as raw materials for the manufacture of electrodes or membranes suitable for use in electrochemical devices such as secondary batteries. [0005] Alkali metal or alkaline earth metal secondary batteries are typically formed by assembling a positive electrode (cathode), an ion-conducting memb...
