摘要 |
A negative active material containing super-conductive nanoparticles coated with a high capacity negative electrode material and a lithium battery including the same are provided, wherein the super-conductive nanoparticles have a structure in which polycyclic nano-sheets are stacked upon one another along a direction perpendicular to a first plane. The polycyclic nano-sheets include hexagonal rings of six carbons atoms linked to each other, wherein a first carbon and a second carbon have a distance therebetween of L1. L2 is a distance between a third carbon and a fourth carbon, and the arrangement of the polycyclic nano-sheets is such that L1 ‰¥ L2. The super-conductive nanoparticle is used as a negative active material in a lithium battery, and the super-conductive nanoparticle increases the capacity, thereby improving the capacity and lifespan of the lithium battery. |
