Abstract
Spherical ceria (CeO(2)) crystallites assembled by nanoparticles were synthesized by hydrothermal treatment of Ce(NO(3))(3)6H(2)O using poly(N-vinyl-2-pyrrolidone) (PVP) as surfactant. It was found that these spheres were developed from the gradual aggregation of small nanoparticles and size of the spheres could be tailored by adjusting the reagent concentrations. Electrochemical tests indicated that thus-prepared CeO(2) spheres exhibited size-dependent discharge capacities and good cyclability in the Li/CeO(2) couple, showing their promising usages as anode materials in the lithium ion battery.Entities:
