MANUFACTURING METHOD FOR ELECTRODE

The present disclosure provides a manufacturing method for the electrode including the electrode mixture layer and the protection layer adjacent thereto on a current collector foil. The manufacturing method includes coating the current collector foil with an electrode mixture slurry and a protection layer formation slurry using a die head including a shim; and drying these slurries. The protection layer formation slurry is subjected to die coating simultaneously with the electrode mixture slurry so that the protection layer formation slurry is adjacent to the electrode mixture slurry. The shim includes a discharge port for discharging the electrode mixture slurry and a discharge port for discharging the protection layer formation slurry. A ratio (B/A) of an opening width B of the discharge port for discharging the protection layer formation slurry to a coating width A of the protection layer formation slurry is 1.00 to 1.07.
