Realization of advanced electrode materials through electrospinning for future secondary batteries |
| 초록 |
Transition metal oxides are very promising electrode materials for lithium-ion batteries that operate through conversion reactions. Energy densities for conversion reactions are higher than for intercalation reactions, but most of transition metal oxides show poor cycling performance and reversibility due to the pulverization of active materials and subsequent volume changes. We here report a facile and scalable synthesis for realizing Li4Ti5O12-coated Fe/Fe3O4 hybrid nanocomposites in the form of one-dimensional nanofibers (C@Fe-Fe3O4/Li4Ti5O12 hybrid NFs). This is a new class of highly-reversible and safe anode material that can significantly reduce the lithium-ion diffusion length and improve strain tolerance during Li ion insertion/extraction. |
