Abstract:
An apparatus for manufacturing an electrode plate of a nonaqueous electrolyte battery to apply an electrode material composition onto at least one of a first surface and a second surface of a rectangular sheet conductive base material having a first side and a second side shorter than the first side, comprising:means for moving the sheet conductive base material in a direction of the first side;a die nozzle disposed in the neighborhood of the surface of the moving sheet conductive base material, for injecting the electrode material composition in a direction substantially perpendicular to the first side;an electrode material composition tank for containing the electrode material composition;supplying pipes connecting the die nozzle and the electrode material composition tank;a pump disposed at the supplying pipes;a valve disposed at the supplying pipes between the pump and the die nozzle;a suction system disposed at the supplying pipes between the valve and the die nozzle; andmeans for drying the electrode material composition, wherein the die nozzle is configured to move in a direction substantially perpendicular to and to separate from the first surface of the sheet conductive base material to form uncoated areas.
