| 英文摘要 | The poor cycling stability and huge volume change of silicon during the charge/discharge processes have seriously hindered the extensive application. In order to deal with address various challenges, silicon/carbon microspheres (SCM) are designed via nonsynchronous nucleation, hydrothermal coupling method and magnesium thermal reduction method. The silicon/carbon microspheres with two carbon shells (SCM-2) delivers the most enhanced initial charge capacity of 2455 mAh g(-1) at 0.1 C, and reveals the highest specific capacity of 2178 mAh g(-1) after 200 cycles and capacity retention of 98% after 500 cycles at 2 C. The SCM-2//LiCoO2 full cell can maintain high capacity of 159.2 mAh g(-1) and no capacity decay after 500 cycles at 0.1 C. It is demonstrated that the fabrication for silicon/carbon microspheres is a convenient and effective strategy to resolve the practical application silicon anode material in lithium-ion batteries. |
