Method for bonding a negative electrode tap of lithium secondary battery, a negative electrode for a lithium secondary battery preparing by applying the same and a lithium secondary battery including the same

摘要

Disclosed are a method for joining a negative electrode tab of a lithium secondary battery, which can join a lithium electrode tab applied as a negative electrode of a lithium secondary battery and a metal lead without damaging the material, a negative electrode for a lithium secondary battery manufactured by applying the same, and a lithium secondary battery including the same. The negative electrode for a lithium secondary battery includes a metal lead having a hole formed therein; at least one lithium electrode tab laminated and joined to each of both sides of the metal lead so as to cover the hole formed in the metal lead; and a bending portion formed at a joining portion of the metal lead and the lithium electrode tab, wherein the lithium electrode tab is characterized in that it is anchor-joined through the hole.
