Abstract

The invention discloses a device for applying slurry. The device comprises a discharging hole, through which active materials are discharged. The discharging hole is slot-shaped. Each of the two inner surfaces of the discharging hole is provided with first and second tilted faces tilting along the width direction, wherein the first tilted face tilts towards the center axis of the length direction of the discharging hole, and the second tilted face tilts towards the center axis away from the length direction of the discharging hole and at the front end of the discharging direction of the active materials. The first tilted face has an inclination angle of 4-14 DEG. The horizontal distance and vertical distance between two edges of the cross section of the second tilted face at the width direction of the discharging holes are respectively 5mm and 7mm.

Description

technical field [0001] Embodiments relate to devices for applying slurry and methods of manufacturing the same. Background technique [0002] A rechargeable battery is a battery that is rechargeable and dischargeable, as opposed to a non-rechargeable primary battery. In the case of a small-capacity battery in which one battery cell is packaged in a pack shape, the rechargeable battery is being widely used as a battery for various portable small electronic devices such as mobile phones, camcorders, and the like. energy source. Furthermore, in the case of a large-capacity battery in which several tens of battery cells are connected to each other, a rechargeable battery is being widely used as an energy source for driving an engine of a hybrid car or the like. Rechargeable batteries are manufactured in various shapes such as cylindrical and prismatic. [0003] A rechargeable battery includes: an electrode group having a separator disposed between a positive electrode and a n...
