The present invention relates to a method for manufacturing a secondary battery. The method for manufacturing the secondary battery comprises: an electrode preparation step of preparing electrodes, each of which is provided with a coating portion coated with an electrode active material and a non-coating portion that is not coated with the electrode active material; an electrode assembly manufacturing step of alternately stacking the electrodes and separators to manufacture an electrode assembly, wherein the electrodes are stacked so that the non-coating portions overlap each other; a non-coating portion bonding step of bonding the non-coating portions to each other; a display part formation step of forming a display part for setting a cutting point on a surface of the bonded non-coating portion of each of the electrodes; and an electrode tab manufacturing step of cutting the bonded non-coating portion adjacent to the display part to manufacture an electrode tab.

Secondary battery and method for manufacturing the same

Systems and methods for executing instructions for executing a virtual reality (VR)-based fire response simulation method for secondary battery production are disclosed. One method includes receiving a gaze direction and gaze location of a user identified from a head mounted display (HMD). Fire response content associated with a secondary battery production apparatus corresponding to the received gaze direction and gaze location is displayed on an area of a display of the HMD. The fire response content includes a plurality of fire response scenarios. User behavior information indicating a motion of the user determined from at least one of the HMD or a controller associated with the HMD is obtained. The fire response content associated with the secondary battery production apparatus is executed based on the obtained user behavior information.

VR-based fire response simulation method and device for secondary battery production

A method for manufacturing an electrode assembly is provided. The method includes a preparation step of preparing a plurality of separators and a plurality of electrodes; an electrode unit manufacturing step of manufacturing an electrode unit having a structure in which the separators and the electrodes are alternately disposed; a pre-sealing step of forming a pre-sealing part in which at least a partial region of each separator of the plurality of separators within the electrode unit are attached to each other; and a separator cutting step of cutting a region of the pre-sealing part. An apparatus for performing the method is also provided.
