Abstract
A notching apparatus and method for an electrode substrate can improve the conventional problem of contamination of an electrode current collector by forming a punching oil supply hole in a punch and applying the punching oil to a wall surface of the punch through the punching oil supply hole, and can also discharge foreign objects generated when punching an electrode through the hole formed in the punch. The notching apparatus for the electrode substrate includes a die member on which the electrode substrate is disposed; and a punch member provided to be spaced above the die member and provided with a punch that moves up and down toward the die member. A wall surface of the punch is provided with one or more punching oil supply holes for applying the punching oil to an outer surface of the punch.
