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: Kits for detecting a target material and methods of detecting a target material by using the kits are provided, the kits include a target material binding portion including a first molecule and a probe linked to the first molecule, and a target material detection portion including a plurality of nanoparticles each having a surface to which a compound having a zwitterion and a second molecule are linked. The first molecule is specifically bound to the second molecule in a pair.
