An exemplary embodiment of the present invention provides a slot (131) die for manufacturing a rechargeable battery electrode for controlling a coating thickness of an active material layer to be uniform, regarding a width (01) of a substrate, by controlling a discharging rate distribution of an active material slurry to be uniform, regarding a width (01) of the slot (131) . A slot (131) die for manufacturing a rechargeable battery electrode includes:a first block (11) ;a second block (30) facing the first block (11) ;and a shim member (33) positioned between the first block (11) and the second block (30) , wherein the first block (11) and the second block (30) are combined to each other to form a slot (131) for discharging an active material slurry, the first block (11) includes a chamber for receiving the active material slurry and forms a first side in a width (01) direction and a discharging direction of the slot (131) , the second block (30) faces the first side to form a second side in the width (01) direction and the discharging direction of the slot (131) , the shim member (33) includes end portions facing each other at respective ends of the first side and the second side and formed in a height direction of the slot (131) , and the end portion (40) includes a width adjuster (A5) protruding to a second reference point (P3) from a first reference point (P2) of the shim member (33) in the width (01) direction by a first adjusting width (Lw), inclined to a third reference point (P4) from the second reference point (P3) with a first angle (81) with respect to the discharging direction, and formed in the discharging direction by a first adjusting length (Ls).
