A hierarchical hybrid of SnO2 nanoparticles encased in graphene oxide nanoribbons (GONRs) are synthesized by a facile, scalable and green method. The effect of different ratio of Sn2+/GONRs in microstructure and electrochemical performance is studied systematically. Both scanning electron microscopy images and transmission electron microscopy images show that SnO2 nanoparticles are anchored onto the surface of GONRs and encased by GONRs to form an integrative framework firmly. The hybrid demonstrated an outstanding rate capability and cycling stability. The highest discharge capacity can reach 514mAhg−1 at rates of 2000mAg−1. Even after 300 cycles, the reversible capacity remains 452mAhg−1 with a retention of 62.7% at current density of 1000mAg−1, which can be attributed to the synergetic effects of SnO2 encased in GONRs.
