The present invention relates to (S1) a charging step of charging charged polymer particles to form charged polymer particles; (S2) transferring the charged polymer particles to at least one surface of the porous polymer substrate to form an electrode adhesive layer, wherein the electrode adhesive layer is formed to have an area of 1 to 30% of the total area of the porous polymer substrate ; And (S3) a fixing step of fixing the electrode adhesive layer with heat and pressure. The present invention also provides a separator manufactured by the method and a lithium secondary battery comprising the separator. According to the present invention, there is provided a process for producing a separator for a lithium secondary battery, in which an electrode adhesive layer is introduced by using static electricity, not by applying a slurry containing a solvent, wherein a solvent is not required by applying polymer particles by a laser printing method, The separator for a lithium secondary battery can be manufactured quickly and the application of only a certain area of the electrode adhesive layer is not limited to the entire area, Can be prevented. |
