    Abstract: The present invention provides method for manufacturing a coated separator for use in an electrochemical device, comprising the steps of: (i) providing a separator having two surfaces; (ii) applying a coating composition [composition (C)] on at least one surface of the separator, the composition (C) comprising a polymer [polymer (P)] and at least one electrolyte salt [salt (E)] of formula (a), A+B− (a) wherein A+ indicates an ion selected from alkaline metal cations or a combination thereof, and B″ indicates an ion selected from anions or a combination thereof, so as to obtain a coating layer onto said surface; and (ii) drying the coating layer so as to obtain a coated separator, wherein the polymer (P) is a vinylidene fluoride (VdF) polymer and comprises recurring units derived from at least one comonomer (C), said comonomer (C) being different from vinylidene fluoride (VdF), and wherein the polymer (P) comprises recurring units derived from at least one (meth)acrylic monomer (MA). Further, the present provides a separator for use in an electrochemical device, said separator being coated on at least one surface thereof a coating comprising a polymer (P) and at least one salt (E) as described above, wherein said coating is characterized by: a dry thickness of from about 0.1 to 10 μm; a weight between 5 and 100% of the weight of the un-coated separator; or being substantially solvent free. Moreover, the present invention provides a method for producing an electrochemical device using the coated separator as described above.
