SECONDARY BATTERY ELECTRODE PANEL CUTTING METHOD

摘要

PURPOSE: A method for cutting an electrode panel is provided to prevent a picked part at a corner part of the electrode panel, concentration of electric charges to the corner part, and slow discharging. CONSTITUTION: A method for cutting an electrode panel comprises: a step of forming a pair of cutting parts which is asymmetric with upper and lower horizontal sides and cutting the cutting parts to contain a pair of curve portions(22), a pair of extension parts(24), and a parallel side(26); and a step of individualizing the electrode panel by a pair of cutting lines.
