A method for producing an anode for a lithium metal secondary battery includes coating a thin film comprised of NbC, TiC or TiCon a substrate; providing a lithium metal electrode; and laminating the thin film to a surface of the lithium metal electrode. Coating is accomplished by providing a dispersion of a powder comprising NbC, TiC or TiC; and coating the dispersion on the substrate by Langmuir-Blodgett scooping (LBS). The method may further include, prior to providing the dispersion, obtaining the powder by etching a MAX phase structure represented by Formula 1, Formula 2 or Formula 3 below:NbAC&#x2003;&#x2003;(1);TiAC&#x2003;&#x2003;(2); andTiAC&#x2003;&#x2003;(3),

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.

A road marker according to exemplary embodiments of the present invention has advantages that exterior impact transmitted from a tire may be absorbed by elastic force of a spring as a consequence of a transparent cover being completely inserted in an upper housing when a vehicle passes on a road marker. The road marker has further advantages in that a vehicle load may not be transmitted to a guide cover and thus breakage of the road marker may be prevented.
