This paper reports a fast microwave-assisted solvothermal approach to fabricate flower-like SnS2and SnO2nanostructures. The synthetic conditions such as microwave-irradiation temperature, reaction time and precursor concentration are found to have critical influences on the product morphologies and sizes. When used as anode materials for rechargeable Li-ion batteries, flower-like SnO2products exhibit better electrochemical properties than as-prepared flower-like SnS2materials. A large reversible capacity of 717 mA h g−1is observed for SnO2nanoflowers with a good cycliability at 100 mA g−1. Moreover, SnO2nanoflowers exhibit superior high-rate performances. Highly stable capacities of 667 and 532 mA h g−1are achieved at 1000 mA g−1and 2000 mA g−1respectively.
