Abstract
Discussed is an electrode notching device for a secondary battery, the electrode for a secondary battery, which is manufactured therethrough, and a secondary battery. The electrode notching device for the secondary battery, which notches a non-coating portion of an electrode sheet to provide an electrode tab, includes: a pair of notching molds configured to press and notch the electrode sheet; and a movement prevention roller part provided on pressing surfaces of the pair of notching molds to prevent the electrode sheet from moving when the electrode sheet is notched.
