SECONDARY BATTERY ELECTRODE PANEL CUTTING METHOD

摘要

PURPOSE: A cutting method of a secondary battery electrode panel is provided to prevent discharging and short of the secondary battery by specifically cutting corner parts of the electrode panel. CONSTITUTION: A cutting method of a secondary battery electrode panel comprises a step of forming cutting parts(20) to correspond to upper and lower lateral planes which cross the longitudinal direction of a reel electrode(10). The cutting parts cut the electrode panel to include a pair of first curved parts(22), a pair of incline parts(24), a pair of a second curved parts(26), and a cutting space in the longitudinal direction of the reel electrode; and cuts the cutting space to be parallel with the longitudinal direction of the reel electrode.
