Abstract
A method of preparing a reinforced separator comprising the steps of:—providing a porous support () on a pre-wetted casting drum ();—applying a dope solution () including a polymer resin and hydrophilic inorganic particles on a side of the porous support other than the side of the porous support in contact with the pre-wetted casting drum;—performing phase inversion () of the applied polymer solution thereby obtaining a reinforced separator; and—removing the reinforced separator () from the casting drum; wherein the casting drum is pre-wetted with a non-solvent for the polymer resin.
