Abstract:
The present invention relates an electrode notching apparatus. The electrode notching apparatus comprises: a notching unit shaping an electrode into a predetermined pattern; a heating unit drying the electrode processed by the notching unit; and a collecting unit collecting the electrode dried by the heating unit, wherein the heating unit comprises: a heating body having a drying space through which the electrode supplied by the notching unit passes; and heating members directly heating a surface of the electrode passing through the drying space to dry moisture remaining on the electrode.
