Abstract: A slot die coater includes a lower die block including a first manifold in which an electrode active material slurry is accommodated, an upper die block including a second manifold in which an insulating coating solution is accommodated, and a shim plate located between the lower die block and the upper die block to form a slot communicating with a discharge port. The shim plate includes a first concave portion provided in a first surface located to cover the first manifold of the lower die block, and a second concave portion provided in a second surface located to cover the second manifold of the upper die block, wherein two second concave portions are configured to be located on opposite sides of the first concave portion in a width direction.

Abstract: Disclosed herein relates to an electrode for a lithium secondary battery and a manufacturing method thereof, and since the electrode for a lithium secondary battery is provided with an auxiliary coating layer containing inorganic particles, a phenolic compound, and a binder at the end of an electrode mixture layer containing an electrode active material, thereby improving energy density of the battery due to an improvement in thickness deviation at the end of the electrode mixture layer, and preventing lithium from being precipitated at the end of the electrode, especially the negative electrode, due to increase in the adhesive strength of the separator at the end of the electrode, it has an advantage of excellent safety.

Abstract: A die coater capable of effectively simultaneously coating a current collector with two types of different liquids, which includes an upper block provided with a second liquid inlet, a lower block coupled to the upper block and provided with a manifold configured to accommodates a first liquid, and coater shims interposed between the upper block and the lower block to form a first slit and a second slit which are separated from each other. The coater shims include a first coater shim which forms a first slit for discharging the first liquid accommodated in the manifold and a second coater shim which forms a second slit for discharging the second liquid supplied through the second liquid inlet. The first coater shim and the second coater shim have the same height, do not overlap vertically, and are placed on the same surface between the upper block and the lower block.

Abstract: An electrode coating device and an electrode coating method are disclosed. An electrode coating device according to an embodiment of the present disclosure includes a slot die coater to apply a slurry to a substrate; and an edge adjusting material providing means providing an edge adjusting material to adjust a protrusion formed at an end of the slurry by contacting the slurry.

Abstract: A die coater shim and die coater for simultaneously coating an electrode slurry and an insulating coating liquid. The die coater shim includes: a base that extends in a width direction; first and second guides that protrude and extend from both ends of the base; an electrode slurry slit that includes a step portion that extends from the base in the width direction between the first and second guides, wherein a thickness of the step portion is smaller than a thickness of the base, and a stepped space that the step portion forms relative to one surface of the base to form an electrode slurry discharge path; and first and second insulating coating liquid slits which include a groove on a surface of each of the first and second guides, wherein one end of the groove forms an insulating coating liquid discharge path.

Abstract: A protective relay test equipment operation device according to an embodiment of the present invention may comprise: a switch unit for, upon reception of a trip signal or a close signal from a protective relay, changing an electrical connection state between a first port configured to be electrically connected to test equipment that generates a test signal and a second port configured to be electrically connected to the protective relay; a measurement unit for measuring a voltage and a current between the first port and the second port during a test period in which an operation time point of the switch unit is a start time point or an end time point; and a calculation unit for calculating a plurality of time point-specific impedance values within the test period according to a measurement result of the measurement unit.

Abstract: Disclosed is a vehicle software control device which includes hardware, a kernel connected to the hardware and configured to execute a first operating system, a system library connected to the kernel, a first connecting unit configured to connect a library for a second operating system different from the first operating system to the system library, and a first application executed on the second operating system.
