The flexible electrode material of SnO2/carbon cloth (SnO2/CC) is fabricated by RF magnetron sputtering method. As an anode material of lithium ion batteries, the SnO2/CC electrode exhibits more excellent cycling stability and rate capability than that of the pure carbon cloth and SnO2. The reversible capacity always maintain about 1.98 mAh/cm2during 50 cycles, which is higher than that of the pure CC (about 1.61 mAh/cm2) and SnO2(about 0.08 mAh/cm2). After 100 cycles, the capacity of SnO2/CC sample is 1.85 mAh/cm2, still retaining 89.4% of the initial capacity. The good electrochemical properties of SnO2/CC are mainly caused by the high surface area, porous structure and the intrinsic soft characteristics of CC, which can effectively accommodate the volume charge during charge and discharge process.
