| 摘要 |
The present invention relates to a method and a device for a positive electrode surface of a lithium secondary battery. A system for transferring a positive electrode active material polymer comprises: a substrate; a polymer supply unit storing and supplying polymers; a polymer generation unit which receives the polymers from the polymer supply unit and thus generates a polymer layer on a surface of the substrate; a heating unit heating the polymers generated on the surface of the substrate; a transferring unit which transfers the polymers generated and heated on the surface of the substrate, on a surface of a positive electrode active material; and a control unit which controls the polymer supply unit, the heating unit, the transferring unit and a polymer coating unit. |
