Embodiment Construction

[0022] Referring to the drawings, the structure and operation of an embodiment of the present invention will be described in detail.

[0023] figure 1 is a schematic perspective view of an electrode assembly 100 for a rechargeable battery manufactured by using a method according to an embodiment of the present invention.

[0024] refer to figure 1 , the electrode assembly 100 may be manufactured by winding such that the electrode assembly 100 has a cylindrical shape. The electrode assembly 100 may include a separator 105 , a first electrode plate 110 , a second electrode plate 120 , a first electrode tab group 130 and a second electrode tab group 140 . For example, the electrode assembly 100 may be formed by winding a first electrode plate 110, a second electrode plate 120, and a separator 105, and the separator 105 may be interposed between the first electrode plate 110 and the second electrode plate 120 such that the first The electrode plate 110 is insulated from the sec...

Abstract

A method of manufacturing an electrode assembly for a rechargeable battery is disclosed. The method includes: providing a first electrode plate comprising an active portion coated with a first active material and an inactive portion extending from an edge of the active portion of the first electrode plate; providing a second electrode plate, the The second electrode plate includes an active portion coated with a second active material and an inactive portion extending from an edge of the active portion of the second electrode plate; providing a separator; winding the first electrode plate, the second electrode plate and the separator, the separator interposed between the first and second electrode plates; and removing a portion of the inactive portion of the first electrode plate and a portion of the second electrode plate A portion of the inactive portion to form a plurality of first electrode tabs for the first electrode plate and a plurality of second electrode tabs for the second electrode plate.

Description

[0001] related application [0002] This application claims the benefit of U.S. Provisional Application No. 61 / 243,908, filed September 18, 2009, and U.S. Patent Application No. 12 / 732,157, filed March 25, 2010, the disclosures of which are incorporated by reference in their entirety here. technical field [0003] Embodiments of the present invention relate to a method of manufacturing an electrode assembly for a rechargeable battery, and more particularly, to a method of manufacturing an electrode assembly for a rechargeable battery by which a plurality of lugs. Background technique [0004] Unlike primary batteries, which cannot be recharged, rechargeable batteries are rechargeable and dischargeable. Rechargeable batteries can be used in a wide variety of applications, including high-tech electronic devices such as cellular phones, laptop computers, camcorders or automobiles. [0005] Each of the rechargeable batteries may include an electrode assembly and an electrolyt...
