Abstract

An electrode assembly and a lithium secondary battery comprising the same are disclosed. Specifically, the present invention provides an electrode assembly which is capable of preventing the occurrence of a short circuit between a non-coating portion of an electrode plate and an active material layer of an electrode plate having an opposite polarity when damage or shrinkage of a separator takes place, through the attachment of an insulating tape to either or both sides of the non-coating portion of an electrode plate without attachment of an electrode tab. Therefore, an internal short circuit of the battery can be prevented by application of the electrode assembly of the present invention to a variety of lithium secondary batteries including pouch-type, polygonal and cylindrical batteries.
