Abstract

In this research, graphene/silicon/carbon composite anode materials were prepared in situ by atmospheric pressure chemical vapor deposition and simple thermal decomposition. The nanosilicon was deposited on the surface of graphene by using SiH4 as a silicon source. Then, the method of pyrolyzing oil-based phenolic resin was used to coat the carbon layer on the silicon surface and agglomerate particles into spherical particles. The capacity retention at a 0.5 C cycle for 140 cycles (1 C = 0.96 A g-1) remained at 810.05 mAh g-1, compared to only 458.16 mAh g-1 for the raw G/Si material.

原位制备高性能石墨烯/硅/碳复合材料作为锂离子电池阳极。

本研究采用常压化学气相沉积和简单热分解的方法原位制备了石墨烯/硅/碳复合负极材料。以SiH4为硅源，在石墨烯表面沉积纳米硅。然后，采用热解油基酚醛树脂的方法在硅表面包裹碳层，使颗粒凝聚成球形颗粒。在0.5 C循环140次（1 C = 0.96 a G -1）时，容量保持在810.05 mAh G -1，而原始G/Si材料的容量保持在458.16 mAh G -1。
