锂离子电池多孔硅/碳复合负极材料研究
Study of Porous Si/C Composite Anode for Lithium Ion Batteries
摘要
Abstract
Excellent cyclic performance carbon-coated porous silicon (c-PS) intended for the fabrication of lithium ion battery anode were synthesized by high temperature solid-state sintering process and hydrothermal method using glucose as carbon source. The phase composition and micro-morphology of the samples were characterized by the X-ray diffractometer (XRD); and scanning electron microscope (SEM); and different mass ratios of Si/C were discussed. The structural stability of porous silicon are sustained; and the electrical conductivity and volume change during repeated cycles of lithium insertion/extraction of composite materials are significantly improved after modification of amorphous carbon. After 100 cycles, the c-PS maintained a reversible capacity of approximately 608. 7 mA· h/g with a capacity attenuation rate of 0. 41% per cycle after 10 cycles.关键词
