Disclosed is an electrolyte for a lithium metal secondary battery and a lithium metal secondary battery including the same. An electrolyte system is intended to maintain the energy density of a secondary battery based on a lithium metal negative electrode and to extend the life of a battery. Particularly, an electrolyte for a lithium metal battery which forms a stable SEI film capable of inhibiting formation and extension of lithium dendrite so that the negative electrode of a lithium metal battery having a high possibility of battery ignition may be stabilized and an internal short-circuit may be prevented, and a lithium metal secondary battery including the same is provided.

In a secondary battery including a separator, the improvement includes a coating layer that is disposed on the separator and that comprises a polyethyleneimine-attached carbonaceous material The secondary battery may include an adhesive buffer layer provided between the separator and the coating layer which imparts adhesion force between the separator and the coating layer. The carbonaceous material adsorbs lithium polysulfides (LiPS) in use to inhibit a shuttling reaction between the anode and the cathode, caused by the dissolution of lithium polysulfides in the electrolyte, and increases recyclability of the lithium polysulfides, resulting in improvement of life characteristics and rate characteristics of the secondary battery.
