▎ 摘  要

Herein, we described a facile method to synthesise porous CoMoO4 nanospheres wrapped with graphene (CoMoO4@G). The porous CoMoO4@G composites were generated from the calcination treatment of CoMo precursors, followed by a graphene-coating process. Compared with pristine CoMoO4 porous spheres, the graphene sheets endowed the CoMoO4@G with higher electrical conductivity and structural stability. When used as an anode materials for lithium-ion batteries (LIBs), the CoMoO4@G electrode delivers a high initial specific capacity (1355.8 mA h g(-1) at 100 mA g(-1)), good cycling stability (783 mA h g(-1) over 150 cycles at 500 mA g(-1)) and excellent rate capacity (697.7 mA h g(-1) at 2000 mA g(-1)). In view of this, the combination of the graphene sheets with CoMoO4 nanospheres serve as potential anode materials for application in the new generation of LIBs.
