[0028] Hereinafter, the present disclosure will be described in detail with reference to FIGS. 1 through 13. However, this is merely illustrative and the present disclosure is not limited to the specific embodiments described illustratively.

[0029] An XYZ coordinate system may be used in this specification. The XYZ coordinate system may be a Cartesian coordinate system.

[0030] For example, the Z-axis can be parallel to the vertical direction. For instance, a positive Z-axis direction can represent the upward direction. For instance, a negative Z-axis direction can represent the downward direction.

[0031] For example, the X-axis can be parallel to the front-back direction. For instance, a positive X-axis direction can represent the forward direction. For instance, a negative X-axis direction can represent the rearward direction.

[0032] For example, the Y-axis can be parallel to the left and right directions. For instance, a positive Y-axis can represent the left direction. For instance, a negative Y-axis can represent the right direction.

[0033] FIG. 1 is a diagram showing an electrode coating device according to one embodiment of the present disclosure coating an active material layer on an electrode sheet metal layer. FIG. 2 is a diagram showing a cross-section of the electrode sheet shown in FIG. 1 cut along A1-A2.

[0034] Referring to FIGS. 1 and 2, the electrode sheet (20) may include an electrode sheet metal layer (21). The electrode sheet metal layer (21) may form a sheet shape.

[0035] The electrode sheet metal layer (21) may be formed from a material including metal. For example, the electrode sheet metal layer (21) may be formed from a material including at least one of aluminum and copper. The electrode sheet metal layer (21) may be referred to as a “current collector.”

[0036] The electrode sheet metal layer (21) can form two sides. For example, one side and the other side of the electrode sheet metal layer (21) can be formed opposite each other. For example, one side of the electrode sheet metal layer (21) can face upward. For example, the other side of the electrode sheet metal layer (21) can face downward.

[0037] The electrode sheet metal layer (21) can form a shape that extends in one direction. For example, the electrode sheet metal layer (21) can form a shape that extends in the front-rear direction. For example, the length direction of the electrode sheet metal layer (21) can be the front-rear direction.

[0038] The electrode sheet metal layer (21) can form a width direction. The width direction of the electrode sheet metal layer (21) may, for example, intersect the length direction of the electrode sheet metal layer (21). For example, the width direction of the electrode sheet metal layer (21) may be parallel to the Y-axis.

[0039] The electrode sheet metal layer (21) can be transported. For example, the transport roll (630) can transport the electrode sheet metal layer (21) in the longitudinal direction of the electrode sheet metal layer (21).

[0040] For example, the transfer roll (630) can transfer the electrode sheet metal layer (21) backward. For example, the transfer roll (630) can transfer the electrode sheet metal layer (21) backward.

[0041] The electrode sheet (20) may include an active material layer (22). The electrode sheet metal layer (21) and the active material layer (22) may form a layer structure. The active material layer (22) may include at least one of an active material, a binder, and a conductive material.

[0042] The active material layer (22) can be applied to one or both sides of the electrode sheet metal layer (21). For example, the electrode coating device (10) can apply the active material layer (22) to one side of the electrode sheet metal layer (21).

[0043] For example, the electrode coating device (10) can apply an active material layer (22) in a slurry state to one side of the electrode sheet layer (21). The active material layer (22) applied to the electrode sheet layer (21) can be dried.

[0044] The thickness of the active material layer (22) formed on the electrode sheet (20) can be determined according to the amount of active material layer (22) drawn from the electrode coating device (10) and the transfer speed of the electrode sheet metal layer (21).

[0045] For example, the thickness distribution in the width direction of the active material layer (22) formed on the electrode sheet (20) can be determined according to the amount of active material layer (22) drawn from the electrode coating device (10) along the width of the electrode sheet (20).

[0046] Therefore, it may be necessary to measure the thickness distribution of the active material layer (22) formed on the electrode sheet (20) in real time and adjust the electrode coating device (10) according to the measured thickness distribution.

[0047] In FIG. 1, the electrode coating device (10) is shown applying an active material layer (22) to an electrode sheet metal layer (21) that is being transported forward, but the scope of the present disclosure is not limited thereto.

[0048] For example, the electrode coating device (10) can apply an active material layer (22) to an electrode sheet metal layer (21) that is transported upward or downward. For example, the electrode coating device (10) can apply an active material layer (22) to an electrode sheet metal layer (21) that is transported at an angle upward or downward.
