摘要： The present disclosure provides a method of preparing a separator for a lithium secondary battery, comprising: (S1) bringing polymer particles into electric charging to obtain electrically charged polymer particles; (S2) transferring the electrically charged polymer particles on at least one surface of a porous polymer substrate to form an electrode-adhesion layer whose area ranges from 1 to 30% based on the total area of the porous polymer substrate; and (S3) fixing the electrode-adhesion layer with heat and pressure.
In accordance with the present disclosure, in the preparation of a separator for a lithium secondary battery, an electrode-adhesion layer is applied by using electrostatic charging, more specifically coating polymer particles by way of laser printing, without the addition of a slurry in a solvent, thereby allowing easy handling and storage and needs no drying step of the solvent to provide cost savings effect as well as rapid and efficient preparation of the separator. Further, the electrode-adhesion layer is applied in a certain area, not the whole area in the separator, thereby preventing an excessive resistance rise in a lithium secondary battery using the separator.

摘要： Disclosed is a separator. The separator includes a porous substrate, and a porous coating layer formed on at least one surface of the porous substrate and including a mixture of inorganic particles and a binder polymer. A continuous or discontinuous patterned layer is formed on the surface of the porous coating layer to allow an electrolyte solution to permeate therethrough. The continuous or discontinuous patterned layer may be formed with continuous grooves to allow an electrolyte solution to permeate therethrough. Due to this structure, the wettability of the separator with an electrolyte solution is improved, shortening the time needed to impregnate the electrolyte solution into the separator.

摘要： The present invention relates to a metal nanobelt and a method of manufacturing the same, and a conductive ink composition and a conductive film including the same. The metal nanobelt can be easily manufactured at a normal temperature and pressure without requiring the application of high temperature and pressure, and also can be used to form a conductive film or conductive pattern that exhibits excellent conductivity if the conductive ink composition including the same is printed onto a substrate before a heat treatment or a drying process is carried out at low temperature. Therefore, the metal nanobelt and the conductive ink composition may be applied very appropriately for the formation of conductive patterns or conductive films for semiconductor devices, displays, solar cells in environments requiring low temperature heating. The metal nanobelt has a length of 500 nm or more, a length/width ratio of 10 or more, and a width/thickness ratio of 3 or more.

摘要： The present invention provides a method for manufacturing a separator, comprising the steps of (S1) preparing a porous planar substrate having multiple pores; (S2) coating a coating solution obtained by dissolving a binder polymer in a solvent and dispersing inoganic particles therein on the porous substrate to form a porous coating layer and drying the porous coating layer; and (S3) applying a binder solution on the surface of the dried porous coating layer to form an adhesive layer, wherein the binder solution has a surface energy of at least 10 mN/m higher than that of the porous coating layer and a contact angle of the binder solution to the surface of the porous coating layer maintained at 80° or more for 30 seconds. In accordance with the present invention, a separator capable of obtaining sufficient adhesion force with minimizing the amount of an adhesive used for the adhesion with an electrode, and minimizing the deterioration of battery performances can be easily manufactured.
