▎ 摘  要

A GeO2/RGO composite was successfully fabricated via alternating deposition of graphene oxide (GO) and GeO2 on the surface of a Ni foam substrate using a facile dip-coating method cooperated with in situ hydrolysis of GeCl4. This material was directly used as a binder-free anode for LIBs and exhibited high reversible capacity (1716 mA h g(-1) at 0.2 A g(-1), 702 mA h g(-1) at 16 A g(-1)), good cycling performance (1159 mA h g(-1) at 1 A g(-1) after 500 cycles) and excellent rate capability. In addition, a reversible capacity as high as 621 mA h g(-1) can be retained when cycled to 500 cycles at a rate as high as 8 A g(-1) .
