Homogeneous β-Co(OH)2 on graphene is synthesized using a simple and effective electrostatic induced spread growth method, which ensures the facile fabrication of a binder-free and mechanically robust CoO/graphene electrode by means of a layer-by-layer stacking process. When employed as an anode in Li-ion batteries, a high rate capability and excellent cycle stability up to 5000 cycles are successfully obtained.
