Abstract
A method for manufacturing electrode plate for secondary battery includes feeding an electrode plate including an active material layer and an uncoated portion to a stamp block on which a pad is formed, applying a punching oil absorbed by the pad to a partial region of the uncoated portion, and notching the electrode plate along the partial region where the punching oil is applied.
Claims14
A method for manufacturing an electrode plate for a secondary battery, the method comprising:
- feeding the electrode plate to a stamp block with a pad, the electrode plate including an active material layer and an uncoated portion;
- applying a punching oil absorbed in the pad to a partial region of the uncoated portion of the electrode plate;
- and
- notching the electrode plate along the partial region where the punching oil is applied.
A stamp punching oil applicator for applying a punching oil to an electrode plate including an active material layer and an uncoated portion, the stamp punching oil applicator comprising:
- a pump configured to feed the punching oil;
- a pad connected to the pump, the pad being made of a porous material and being configured to absorb the punching oil from the pump;
- and
- a stamp block that supports the pad, the stamp block being configured to move in a direction perpendicular to a surface of the electrode plate, and being configured to apply the punching oil absorbed in the pad to a partial region of the electrode plate.
