Beschreibung
Zusammenfassung:	High energy density lithium secondary batteries are disclosed herein. In some embodiments, a high energy density lithium secondary battery includes a cathode, an anode, and a separator. The cathode includes a first cathode active material having a layered structure and a second cathode active material having a spinel structure, wherein the amount of the first cathode active material is between 40 and 100 wt % based on the total weight of the cathode active materials. The anode includes crystalline graphite and amorphous carbon as anode active materials, wherein the amount of the crystalline graphite is between 40 and 100 wt % based on the total weight of the anode active materials.
