Abstract: A device for cooling a slurry manufacturing mixer-comprises: a rotation container that comprises a mixing part, which mixes slurry and has a temperature detection part, and a slurry discharge part, which is formed under the mixing part and has a discharge hole for discharging the slurry; a body that is positioned under the rotation container and has a through-hole formed therethrough, through which the rotation container is inserted; and a sealing member interposed between the rotation container and the body, wherein the mixing part comprises an inner container and an outer container, and a cooling water passage is formed between the inner container and the outer container.

Abstract: The present invention relates to a device for cooling a slurry manufacturing mixer, wherein a cooling water passage is formed between an inner container and an outer container and cooling water is supplied to the cooling water passage so as to quickly cool a rotation container for manufacturing slurry and slurry therein.

Abstract: An apparatus and method for coating a functional layer on a current collector with an active material layer thereon, the apparatus including a first roll and a second roll, the first roll and second roll being for advancing the current collector; a gravure roll, the gravure roll being configured to coat the functional layer on the active material layer; a thickness measurer, the thickness measurer being configured to measure at least one of a thickness of the active material layer and a sum thickness of the active material layer and the functional layer; and a controller, the controller being in communication with the thickness measurer and being configured to control a rotation speed of the gravure roll.

Abstract: An apparatus detecting the position of the functional layer of the electrode plate includes a first electrode plate sensor disposed at a side of a material to sense start points of electrode plates continuously formed on the material at uniform intervals, a second electrode plate sensor disposed at an other side of the material to sense a length of the electrode plate, a functional layer sensor provided behind the first electrode plate sensor and the second electrode plate sensor above a material traveling direction to sense position and length of the functional layer formed on the electrode by sensing a difference in color, and a controller feeding back a feedback result indicating whether the functional layer is correctly coated through values sensed by the first electrode plate sensor, the second electrode plate sensor, and the functional layer sensor.
