Abstract
A negative electrode for a lithium secondary battery using lithium metal for the negative electrode and a method for manufacturing the same. The method includes forming a protective layer for dendrite prevention of the negative electrode. The method for manufacturing a negative electrode may be achieved by a process including coating a slurry containing fluorocarbon and/or fluorinated metal dispersed in a solvent onto a lithium metal layer and drying the slurry.
