SnO2-based anodes with high capacity are appealing for Li-ion batteries (LIBs). However, the large volume change and inferior cycling stability limit their practical application. To mitigate these problems, a novel nanocomposite of silicon-incorporated SnO2 with graphene sheets (STOG) has been successfully fabricated as anode material for LIBs. Through a simple hydrolysis process, ultrafine Si-incorporated SnO2 (STO) nanoparticles are uniformly loaded on the graphene sheets. Further it is found that Si incorporation brings about the Si-O-Sn bonding in the SnO2 matrix and strengthens the Sn-O-C bonding between STO and graphene. These merits can enhance the structural stability and electron/ion transport of STOG nanocomposite, facilitating the reversible conversion of Sn-SnO2. As a result, this STOG material delivers a high discharge capacity of 1117.8 mAh g(-1) and retains 92.5% of the second capacity after 100 cycles at 0.1 A g(-1). Furthermore, an excellent rate capacity of 683.9 mAh g(-1) can be obtained at a high current of 1 A g(-1). This work provides an effective way to design high-performance SnO2-based anode material for LIBs.
