Cathode electrode, method for manufacturing the same and lithium battery containing the same

摘要

Provided is a cathode electrode having a cathode active material layer stacked on a current collector. The cathode active material layer includes a conductive material having a surface coated with sulfur and/or pores filled with sulfur. Also, provided is a lithium secondary battery employing the cathode electrode. Since the structure of the cathode active material layer can be maintained even at phase transition of sulfur during charging and discharging, the cathode electrode is structurally stable during charging and discharging.
