Abstract: A current collector for a secondary battery has a material having an elongation of 1.5 to 3.0% and a tensile strength of 25 to 35 kgf/mm2. An electrode, an electrode assembly, cylindrical battery cell, and battery pack are also provided.

Abstract: An electrode assembly including a first electrode, a second electrode, and a separation file interposed between the first electrode and the second electrode, the first electrode, the second electrode, and the separator being wound in one direction about a winding axis is provided. Each of the first electrode and the second electrode has a sheet shape with a pair of long sides and an uncoated portion not coated with an active material layer on one of the long sides. The first electrode includes at least one insulation layer that simultaneously covers a portion of the uncoated portion and a portion of the coated portion. A cylindrical battery cell and a battery pack are also provided.

Abstract: Provided is a diabetes management method and system. A diabetes management server includes a database defining a monitoring procedure for at least two patient groups. When receiving a blood sugar measurement value from a user terminal, the diabetes management server generates feedback information about the blood sugar measurement value by using a monitoring procedure for a patient group including the user and then transmits the feedback information to the user terminal or the like.
