发明名称 AQUEOUS VINYLIDENE FLUORIDE POLYMER LATEX
摘要 The present invention pertains to an aqueous composition comprising: (A) an aqueous latex comprising at least one vinylidene fluoride (VDF) polymer [polymer (F)] comprising recurring units derived from vinylidene fluoride (VDF) and at least one (meth)acrylic monomer (MA) having formula (I) here below: wherein: —R1, R2 and R3, equal to or different from each other, are independently selected from a hydrogen atom and a C1-C3 hydrocarbon group, and —ROH is a hydrogen atom or a C1-C5 hydrocarbon moiety comprising at least one hydroxyl group, (B) at least one powdery electrode material, and (C) optionally, less than 10% by weight, based on the total weight of the aqueous composition, of at least one organic solvent (S), wherein the polymer (F) in the N aqueous latex is under the form of primary particles having an average primary particle size of less than 1 μm, as measured according to ISO 13321. The present invention also pertains to a process for manufacturing an electrode using said aqueous composition, to an electrode comprising a metal substrate coated on at least one surface with said aqueous composition and to use of said electrode for manufacturing a non-aqueous-type electrochemical device.;
