Abstract: A method for manufacturing a catalyst for oxidative dehydrogenation reaction, a catalyst for oxidative dehydrogenation reaction, and a method for manufacturing butadiene using the same.

Abstract: Disclosed are an autonomously traveling mobile robot and a traveling control method thereof, which can control the traveling of the mobile robot according to a first traveling mode in which the mobile robot travels by following obstacles located around the mobile robot or a second traveling mode in which the mobile robot travels in consideration of a positional relation with an existing traveling trajectory through which the mobile robot has already traveled, and generate candidate spots where the mobile robot can travel while the mobile robot travels along the traveling trajectory to implement a spiral cleaning pattern.

Abstract: A battery includes an electrode assembly, a case accommodating the electrode assembly, a cap plate sealing an upper portion of the case, a coupling pin elongated downwardly from the cap plate to the electrode assembly such that the coupling pin is concave when the cap plate is viewed from above and convex when the cap plate is viewed from below, and an electrode lead coupled to the coupling pin which electrically connects the coupling pin and the electrode assembly to one another. The battery may have a simple structure, reduced electrical resistance, an improved output performance.

Abstract: A battery includes an electrode assembly, a cap plate comprising an electrode terminal, and an electrode lead coupled to the cap plate, wherein the electrode lead electrically connects the electrode assembly and the electrode terminal and the cap plate and the electrode lead are coupled at the center of the electrode lead, which may reduce an electric resistance of a charge/discharge path and improve output performance of the battery.

Abstract: An electrode assembly and a secondary battery having an electrode tab are disclosed. In one aspect, the electrode assembly includes first and second electrodes which are wound with a separator placed therebetween. The first electrode includes a first coated portion, and a plurality of first electrode tabs T1-Tn not coated with an active material and protruding outwardly from the first coated portion, wherein n is greater than 2. The first electrode, when spread in a plane form, includes first to nth portions on which the first electrode tabs T1-Tn are respectively formed, wherein the first and nth portions respectively define the innermost and outermost portions thereof. The distance between the first electrode tab Tn placed at the outermost portion and the first electrode Tn?1 placed at the second outermost portion is greater than any of the distances between two adjacent ones of the other first electrode tabs T1-Tn?1.
