Patent attributes
An electrode plate manufacturing method of the present disclosure uses an electrode plate manufacturing apparatus including: a first roll and a second roll facing each other at a first position; and a third roll facing the second roll at a second position, and the manufacturing method rotates the first to the third rolls, feeds an electrode material at the first position, and brings a current collecting foil to pass through the second position. The electrode plate manufacturing apparatus includes: a flow passage roll having a flow passage thereinside and an outer circumferential surface disposed to be in contact with an outer circumferential surface of at least one of the first roll, the second roll, and the third roll; and a circulating unit circulating a fluid through the flow passage. The circulating unit circulates the fluid through the flow passage of the flow passage roll during manufacturing the electrode plate.
