Abstract: A secondary battery according to an embodiment of the present disclosure includes an electrode assembly to which an electrode lead is attached; a case accommodating the electrode assembly so that a portion of the electrode lead is exposed to the outside; a sealing portion formed in the case to seal the electrode assembly; and a lead film covering a portion of an outer surface of the electrode lead and interposed between the electrode lead and the sealing portion, wherein the electrode lead includes a first region not corresponding to the lead film and exposed to the outside of the case, a second region corresponding to the lead film, and a third region not corresponding to the lead film and not exposed to the outside of the case, wherein a separation groove may be located in the third region.

Abstract: Provided is a pixel driving circuit including a first circuit configured to control, in a data writing mode, a signal related to driving of one or more light-emitting elements, and a second circuit configured to supply, in a driving mode, power to the one or more light-emitting elements based on a signal transmitted from the first circuit.

Abstract: Disclosed are a resin composition for a cable material and a cable used for a vehicle and a method of manufacturing the cable thereof. In particularly, by controlling the components such as a polypropylene content, a flame retardant content and the like in a base resin, and containing a high crystalline homo polypropylene (PP) resin and a high crystalline block polypropylene resin in the base resin in a specific ratio, the resin composition provides excellent physical properties such as abrasion resistance and flexibility resistance and has reduced weight effect when a cable is manufactured using the resin composition.

Abstract: A method of manufacturing a magnetic substance includes forming crack lines arranged in one direction on a magnetic sheet by crushing the magnetic sheet to divide the magnetic sheet by the crack lines; stacking the magnetic sheet with other magnetic sheets into layers; and press-processing the stacked magnetic sheets.
