The present invention pertains to an aqueous dispersion of a vinylidene fluoride polymer having a high molecular weight and possessing a substantially linear structure, leading to reduced amount of gels/insoluble fractions, to a method for its preparation and to its use for the manufacture of electrochemical cell components, such as electrodes and/or composite separators or for the manufacture of membranes.

Vinylidene fluoride polymer dispersion

Provided are fluorinated block copolymers comprising alternating hard blocks and soft blocks, wherein both said hard and soft blocks comprise vinylidenfluoride (VDF). Also provided is the use of said block copolymers in applications for lithium batteries including an electrochemical cell and a separator for an electrochemical cell which is coated with a composition comprising the fluorinated block copolymers. Further provided is a process for the manufacture of the separator.

Fluorinated block copolymers and application thereof

The present invention relates to a method for stabilizing aqueous dispersions, notably of polymers based on vinylidene fluoride (VDF), and to the use of the stabilized aqueous dispersion thus obtained in electrochemical applications.
