| Outline of Final Research Achievements |
For efficient preparation of high-capacity anode materials for lithium-ion battery, silicon (Si) / carbon composites were prepared through the liquid pulse injection (LPI) technique. Homogeneous composites could be prepared using a mixture of Si nanoparticles, carbon source and catalyst source as an initial material. The obtained composites have higher discharge capacity and cyclability than those of a mechanical mixture of Si nanopartilces and carbon nanofibers (CNFs). Because this technique is low-cost and easy for scale-up, this work should contribute toward industrial usage of high capacity Si anode.
