Abstract:
1. A negative electrode active material comprising nanometal particles and super-conductive nanoparticles, each of the nanometal particles having a diameter in a range of about 300 to about 500 nm, each of the super-conductive nanoparticles comprising n polycyclic nano-sheets, each of the n polycyclic nano-sheets comprising hexagonal rings, each of the hexagonal rings comprising 6 interconnected carbon atoms, each of the hexagonal rings being fused to at least another one of the hexagonal rings, the hexagonal rings of each of the n polycyclic nano-sheets being arranged substantially in a plane, the n polycyclic nano-sheets being stacked in a direction normal to the plane, n being an integer in the range of 2 to 100, and each of the super-conductive nanoparticles having first and second carbon atoms respectively located in the n polycyclic nano-sheets, the first carbon atom being regarded as the origin A (0, 0, 0) of an x, y, z coordinate system and the second carbon atom having a coordinate B (a, b, c), d
