Solvothermal Synthesis of Yolk–Shell CeVO 4 /C Microspheres as a High‐Performance Anode for Lithium‐Ion Batteries

Yolk–shell CeVO 4 /C microspheres are fabricated by a facile solvothermal method, followed by a carbonization process, by using glucose as a precursor. The hierarchical structures supply a high specific surface area and alleviate volume changes during the lithiation–delithiation process. Owing to the unique porous structural features, the yolk–shell CeVO 4 /C microspheres present a high lithium storage capacity, reaching 580 mAh g −1 at a current density of 100 mA g −1 . Furthermore, the microspheres exhibit good cycle stability and high rate performance, for example, in the 100th cycle they display a capacity of 448 mAh g −1 at a current density 100 mA g −1 and a capacity of 292 mAh g −1 at 1000 mA g −1 in the 40th cycle; these values are better than those of pure‐phase yolk–shell CeVO 4 microspheres.
