Abstract

The present invention relates to a system for manufacturing a jelly roll by winding a cathode, an anode and a separator in a process of manufacturing a jelly roll which is composed in a lithium ion battery for a vehicle. A process for manufacturing a lithium ion secondary battery is divided into an electrode manufacturing process and an assembly process, wherein the electrode manufacturing process is divided into stirring, application, drying and compression cutting (slitting); and the assembly process is divided into winding, jelly roll insertion and electrolyte insertion, and encapsulation. The characteristics of the lithium ion secondary battery vary greatly according to the states of the cathode and the anode, a stacking method and a winding method. Therefore, the present invention provides the system for manufacturing a lithium ion battery jelly roll for an electric vehicle and the method for manufacturing a jelly roll, capable of providing a high efficiency lithium ion secondary battery by enabling stable winding without deforming a cathode plate as an electric shock is prevented and a winding starting point is reinforced via cutting and chamfering effects by enabling the cutting surface of the cathode to be taped when composing the cutting surface into one pattern unit of the jelly roll in the process of manufacturing the jelly roll by winding the manufactured cathode, anode and separator.

Description

technical field [0001] The present invention relates to a system and method for producing a core pack by winding an anode, a cathode, and a separation membrane in a production process of a core pack for a lithium-ion battery for an automobile. Background technique [0002] In general, lithium-ion batteries cannot be commercialized because of the high reactivity of lithium, which makes it difficult to solve safety problems. Commercialization has not begun until recently, but lithium-ion batteries have many advantages compared with other batteries. [0003] First, because lithium metal is lighter than any other metal, lithium-ion batteries are very light and have high energy density. Second, the electromotive force of lithium-ion batteries is large. Third, since there is no memory effect (memory effect: the property that the battery must be fully discharged before charging), it can be charged even when it is charged to a certain extent without being fully discharged. Fourth,...
