Sn-Based materials are considered as promising anode materials for lithium ion batteries due to their high theoretical capacities; however, aggregation of electrochemically active particles and pulverization resulting from huge volume changes during alloying/dealloying severely limit their performance. To solve these problems, nanosized and hollow structures have been proposed. Herein, uniform solid Sn nanoparticles and hollow/amorphous SnOx nanospheres are prepared accordingly and their electrochemical performances as anode materials in lithium ion batteries have been evaluated. Uniform solid Sn nanoparticles deliver a capacity of 416.4 mA h g(-1) for 400 cycles at a current of 500 mA g(-1), corresponding to a high capacity retention of 81.1%. Furthermore, hollow/amorphous SnOx nanospheres show a high capacity retention of 81.3% for 400 cycles at a current of 500 mA g(-1) and exhibit a good rate capability (retains 58.0% of the capacity at 1000 mA g(-1) with respect to 100 mA g(-1)). It is believed that their good electrochemical performances mainly originate from their small sizes (<20 nm) and unique nanoarchitectures.
