GeO 2 /graphene composites are synthesized for the first time . Characterizations reveal the homogeneous dispersion of GeO 2 nanoparticles (40–100 nm) on the non‐aggregated graphene nanosheets. As anode material for Li ion batteries, the composites exhibit remarkably high reversible capacity (1110.6 mAh g −1 ), excellent cycling stability (90.0% after 50 cycles), and superior rate capability (≈540 mAh g −1 at 3 A g −1 ).
