A composite separator, a preparation method therefor, and a use thereof. The composite separator comprises a nanofiber membrane and a hydrophobic polymer resin layer, the nanofiber membrane comprising a nanofiber layer, and the hydrophobic polymer resin layer being modified on at least one surface of the nanofiber layer. The ratio of the average volumetric pore size of the hydrophobic polymer resin layer to the average volumetric pore size of the nanofiber membrane is 1.3-1.75. By means of controlling the average volumetric pore size of the hydrophobic polymer resin layer to be greater than the average volumetric pore size of the nanofiber membrane, and controlling the pore size ratio of the two to be within a specific range, the hydrophobic polymer resin layer can not only facilitate the discharge of moisture from the nanofiber membrane in a drying stage during preparation, but also effectively prevent the nanofiber membrane from absorbing moisture in the air, thereby allowing the moisture content of the composite separator to be relatively low. In addition, the pore size ratio of the two being within a specific range also helps prevent lithium ion conduction from being affected by pore blockage of the nanofiber membrane.
