Separator Coating For Li Ion Batteries Based On Pvdf Acrylate Latex

Abstract: The invention relates to a coating based on a fluoro acrylate polymer latex comprising inorganic particles, said coating exhibiting a very good compromise between, on the one hand, dry adhesion and adhesion in the wet state, and, on the other hand, between adhesion and ionic conductivity. This coating is intended for a separator application, in particular for Li-ion batteries. The invention also relates to a Li-ion battery comprising a separator covered with such a coating.
