METHOD FOR COATING INORGANIC PARTICLES ON LITHIUM SECONDARY BATTERY SUBSTRATE, AND LITHIUM SECONDARY BATTERY INCLUDING SUBSTRATE COATED BY THE METHOD |
摘要 |
The present invention provides a method of coating a substrate for a lithium secondary battery with inorganic particles, comprising charging the inorganic particles to form charged inorganic particles; transferring the charged inorganic particles on the substrate for a lithium secondary battery to form a coating layer; and fixing the coating layer with heat and pressure. Such a coating method according to one embodiment of the present invention uses electrostatic force without the addition of a solvent, and therefore, non use of a solvent can result in cost-reducing effects since there is no burden on the handling and storing of the solvent, and since a drying procedure after slurry coating is not needed, it allows for the preparation of a lithium secondary battery in a highly effective and rapid manner. |
