Abstract
An electrode assembly comprising an electrode tab or an electrode plate substrate which has an identification mark formed thereon and a lithium rechargeable battery using the same are disclosed. This identification mark makes it possible to easily check the record of the manufacturing processes of the battery, including production equipment, production date, line operators, and production lines when a battery malfunctions. This identification mark may prevent a replica of the defective component from being manufactured.
