Abstract

Abstract: In this work, highly uniform Sb doped SnO2 nanospheres with different Sb doping concentrations were prepared by a hydrothermal method. Compared with the pure SnO2 material, the obtained SnO2 :Sb nanospheres exhibits significantly enhanced lithium storage performances in both of the initial capacity and the cycling stability, severed as anode materials for lithium-ion batteries. Among the SnO2 :Sb materials provided in this work, the SnO2 :Sb nanospheres with 6 at% of Sb dopants delivers a highest discharge capacity of 1575 mA h g −1 (charge capacity of 914 mA h g −1 ) at the first cycle and excellent cyclability (588 mA h g −1 at 100th cycles), due to the reduced crystalline size and the improved electrical conductivity induced by Sb dopants.
