In this work, the tin dioxide/reduced graphene oxide (SnO 2 /rGO) hybrid with 3D porous architecture has been prepared by a straightforward and environmentally friendly one‐step solvothermal method, in which superfine SnO 2 nanoparticles are well‐proportioned immobilized on rGO. When applied as anode material for lithium‐ion batteries (LIBS), the prepared SnO 2 /rGO hybrid demonstrates superior electrochemical properties. It can be achieved high initial cycle reversible capacity of 1058 mA h g −1 and retained a stable discharge capacity of 1104 mA h g −1 after 200 cycles at 0.1 A g −1 . Remarkably, a high capacity of 750 mA h g −1 can be kept after 500 cycles at 0.5 A g −1 . These consequences manifest that the obtained SnO 2 /rGO hybrid is a promising anode material for LIBS.
