摘要：
The present invention provides a cathode produced from a cathode slurry comprising: (a) a cathode active material based on a lithium-containing metal composite oxide or a chalcogenide compound; and (b) an ionic liquid, as well as an electrochemical device including the cathode. The inventive cathode can greatly improve the safety of batteries without causing a significant deterioration in the battery performance.
