An apparatus for pressing a battery cell includes a first pressing plate and a second pressing plate spaced from the first pressing plate to receive a battery cell therebetween and to press the battery cell. At least one of the first pressing plate or the second pressing plate is formed of a shape memory material to provide a pressing member.

A negative electrode for a lithium secondary battery including a protective layer formed with a conductive fabric, in particular, to a negative electrode for a lithium secondary battery including a conductive fabric formed on at least one surface of the lithium metal layer and having pores, and a lithium secondary battery including the same. The lithium secondary battery including a negative electrode having the conductive fabric as a protective layer that induces uniform reactions within the pores, thus preventing local lithium metal formation on the lithium metal surface, and thereby suppressing dendrite formation on the lithium metal surface, and thereby suppressing dendrite formation and cell volume expansion. In addition thereto, mechanical stability can be maintained even when lithium plating and stripping occurs due to the flexibility and tension/contraction of the conductive fabric.
