| Abstract Scope |
An attractive candidate as the anode material for lithium-ion battery is β-SiC. One of major problems to develop the semiconductive β-SiC as the anode material is the loss of conduction pass inside the materials just like Si and SiO. β-SiC possesses zinc blend type of cubic structure with regularly stacked three close packed layers. We found that stacking-sequence disordered SiC (SD-SiC), not the three dimensionally ordered crystal like cubic β-SiC, with amorphous carbon as conduction pass worked as the anode material with the high discharge capacity in the half-cell with Li as the counter electrode. In this work, the synthesis of SD-SiC with amorphous carbon, the characterization, the discharge property and the cycle performance in the half-cell will be described. |
