This cover picture shows a new simple and environmantal friendly fabrication approach to prepare Cu6Sn5 nanoparticles, which is a kind of intermetallic compound (IMC) with active/inert Sn-Cu interfaces. The active layer reacts with Li+ and the inert layer inhibits the volume change effectively. Meanwhile, reduced oxide graphene (RGO)/Cu6Sn5 composites are also prepared by the similar method for the reason that the presence of RGO alleviats the aggregation of Cu6Sn5 nanoparticles. This unique structure of RGO/Cu6Sn5 nanocomposites exhibits promising cycling stability (461 mAh·g-1 after 18 cycles), high rate capability and prominent capacity retention, which can be extensively used in the field of lithium-ion battery anode.
