| 제목 | Fabrication of silicon coated MWCNT with magensiothermic reaction and its application to negative electrode for lithium-ion batteries |
| 초록 | There have been many efforts to increase energy density of lithium-ion batteries (LIBs), such as investigation of the materials with higher specific capacity, for emerging new applications. Among prospective materials, silicon is the most promising material due to its high energy density and abundance. Silicon, however, still has some problems related to low electric conductivity and large volume expansion. In this research, we make silicon coated MWCNT with magnesiothermic reaction and apply this material to anode material for LIBs. MWCNT can relieve the problem related to low electric conductivity of silicon. And intrinsic pores produced by assembly of MWCNT can be benefit for enduring volume expansion of siilcon during the reaction with lithium. |
