Provided herein is a device for forming a conductive film. The device includes a deposition device and an air supply. The deposition device is configured to form a wet film having conductive nanostructures and a fluid carrier on a web. The web is moved in a first direction while forming the wet film. The air supply is disposed at a side of the web and configured to apply an air flow onto the wet film. The air flow is directed onto the wet film in a second direction perpendicular to the first direction to reorient a direction of some conductive nanostructures in the wet film to define reoriented conductive nanostructures.

Methods and apparatuses for applying coatings (9) on a moving web (3) are provided. A slot die (20) and a back-up roll (11) engage with each other. The back-up roll has a deformable inner layer (12) with a surface thereof covered by a deformable outer layer (14). The slot die and the flexible web at a contacting area are impressed into the back-up roll with an engagement depth D, which enables formation of a coating having a substantially uniform thickness.

The present invention relates to a double slit coating die, and an electrode active material coating apparatus comprising same, the double slit coating die comprising first to fourth blocks which are positioned sequentially adjacent to each other, and having a structure in which the positions of the first and second blocks can move in a direction tilted at an angle θ with respect to the interface between the second and third blocks. The present invention has the effects of preventing slip surfaces between blocks constituting the die from spreading apart, and reducing offset in a coating process.

The present invention relates to electrode slurry coating apparatus and method, the present invention ultimately allowing the process efficiency to be increased and rate of errors to be reduced when double-layer structured active material layers are formed by temporally adjusting the height of first and second discharge outlets through which active material is discharged.

An applicator system for applying a material to a substrate is disclosed, the applicator system having a nozzle assembly that includes a nozzle having a nozzle head. The nozzle assembly also includes a baffle plate including a cutout that extends through the baffle plate, where the baffle plate is received by the nozzle head such that the nozzle head and the baffle plate define a cavity. The nozzle assembly further includes a cover plate attached to the nozzle head such that the cover plate secures the baffle plate within the nozzle head, where an outlet passage is defined between the baffle plate and the cover plate, the outlet passage being fluidly connected to the cavity through the cutout of the baffle plate.

A slot die for manufacturing a rechargeable battery electrode includes a first block with a chamber to accommodate an active material slurry, a second block facing and attached to the first block, a shim between the first and second blocks and including facing end portions, and a slot between the first and second blocks, and between the facing end portions, the slot including a first side defined by the first block, and a second side defined by the second block and facing the first side. Each of the end portions of the shim includes a width adjuster protruding to a second reference point from a first reference point in a width direction by a first adjusting width, extending to a third reference point from the second reference point at a first angle with respect to a discharging direction, and having a first adjusting length in the discharging direction.

According to one embodiment, a system for manufacturing a polymethyl methacrylate (PMMA) prepreg includes a mechanism for continuously moving a fabric or mat and a resin application component that applies a methyl methacrylate (MMA) resin to the fabric or mat. The system also includes a press mechanism that presses the fabric or mat during the continuous movement subsequent to the application of the MMA resin to ensure that the MMA resin fully saturates the fabric or mat. The system further includes a curing oven through which the fabric or mat is continuously moved. The curing oven is maintained at a temperature of between 40° C. and 100° C. to polymerize the MMA resin and thereby form PMMA so that upon exiting the curing oven, the fabric or mat is fully impregnated with PMMA.
