More Information
Summary:The present invention relates to a lithium electrode and a lithium secondary battery including the same. More specifically, the thickness and the surface roughness of a surface oxide film included inthe lithium electrode are controlled so as to prevent a side reaction with polysulfide when the lithium electrode is applied as an anode of a lithium secondary battery, for example, a lithium-sulfur secondary battery, thereby enabling battery life to improve. 本发明涉及一种锂电极和一种包含所述锂电极的锂二次电池，并且更具体地，通过控制所述锂电极中包含的表面氧化层的厚度和表面粗糙度并使用所述锂电极作为锂二次电池如锂硫二次电池的负极，可以通过抑制与多硫化物的副反应而提高电池寿命。
