A separator for a lithium battery includes a porous coating layer disposed on a surface of a porous base, and a first adhesive layer including a plurality of dots disposed at intervals at a surface of the porous coating layer, the plurality of dots of the first adhesive layer penetrating through the porous coating layer to be on the surface of the porous base.

Separator for lithium battery, lithium battery including the same, and method of manufacturing the lithium battery

A secondary battery includes an electrode assembly designed to prevent an internal short circuit. The electrode assembly includes an electrode group formed by stacking and winding a first electrode plate, a separator and a second electrode plate, and a tape is attached to upper and lower parts of an end of the electrode group. An end of the separator is exposed externally, and the tape is attached to upper and lower parts of the end of the separator. Furthermore, a secondary battery having the electrode assembly is provided.

Electrode assembly and secondary battery having the same

An electrode assembly includes a positive electrode including a positive electrode current collector and a positive electrode active material layer on the positive electrode current collector, a negative electrode including a negative electrode current collector and a negative electrode active material layer on the negative electrode current collector, and a separator between the positive and negative electrodes, the separator including a heat-resistive unit and a lubrication unit, the heat-resistive unit having a heat-resistive material, and the lubrication unit being at an inner front end of the spirally winding separator and having a friction coefficient that is lower than that of the heat-resistive unit.

Electrode assembly and rechargeable battery using the same

A lithium secondary battery includes an electrode assembly where a negative plate and a positive plate are rolled in the form of a spiral while interposing a separator with a modulus of elasticity of around 2.0 kg/mmor less in the longitudinal direction. A can, inside of which the electrode assembly is mounted together with an electrolyte, is electrically connected to one of the negative plate and the positive plate of the electrode assembly. A cap assembly is fitted to the top of the can, and is electrically connected to the other of the positive plate and the negative plate of the electrode assembly.

Lithium secondary battery and separator therefor
