Provided are an anode for a secondary battery including an anode collector, an anode active material coated on the anode collector, and a non-coating portion (anode tab) which protrudes from one side of the anode collector and is not coated with an anode active material, wherein the anode includes a metal member which is bonded to the non-coating portion and has higher reactivity or reducibility with respect to a metal oxide than the anode collector, and a secondary battery including the anode.

Anode for lithium secondary battery and lithium ion secondary battery including the same

Provided is an electrode assembly, and more particularly, an electrode assembly having a structure wound in a state, in which a plurality of unit cells having a stacking structure is disposed on a long sheet type separation film, and including the unit cells having two or more types of configurations of electrode materials, wherein a separator stacked on the unit cell having a stacking structure has a coating material coated on both sides thereof and the long sheet type separation film has a coating material coated on one side thereof. According to the present invention, an electrode assembly improving processability of preparation of a battery while reducing initial resistance during the preparation of the battery as well as having battery lifetime equivalent to that of a conventional battery and a lithium secondary battery including the electrode assembly may be provided.

Electrode assembly and lithium secondary battery including the same

The present invention relates to novel cephalosporin derivatives represented by Chemical Formula 1. Wherein, X, Y, L, R, and Rare as same as defined in the description of the invention. The present invention also relates to pharmaceutical antibiotic compositions comprising a novel celphalosporin derivative represented by Chemical Formula 1, a prodrug thereof, a hydrate thereof, a solvate thereof, an isomer thereof, or a pharmaceutically acceptable salt thereof as an effective ingredient. Compounds of the present invention are effective ingredients for the broad spectrum of antibiotic resistance, exhibit low toxicity, particularly in Gram-negative bacteria, which can be useful with strong antimicrobial activity.
