Abstract

The severe volume change and aggregation of silicon nanoparticles (SiNPs) when used as an anode for lithium ion batteries (LIBs) are the key issue. Here, we demonstrate a novel approach to wrapping SiNPs in three-dimensional reduced graphene oxide (RGO) aerogel. The RGO aerogel not only provides a porous network for entrapping SiNPs to accommodate the volume change during cycling, but also facilitates electrolyte transport. Furthermore, the continuous RGO network is favourable for electron transfer. The graphene-wrapped SiNPs were stable and displayed an excellent rate capacity, delivering a reversible capacity of about 2000 mA h g^-1 after 40 cycles.
