Abstract
A composite material is provided. The composite material includes carbon layers and metal compound layers alternately and repeatedly stacked. Each of the metal compound layers includes molybdenum and selenium. When the composite material is used as a positive active material for a lithium selenium secondary battery, selenium is separated from the metal compound layer through a preliminary charge/discharge process. In addition, the composite material may be used as negative active materials of a lithium ion battery and a lithium ion capacitor. Furthermore, the composite material may be used as an active material of a positive electrode of the lithium selenium secondary battery.
