Enhanced electrochemical performance of CoMoO4 nanorods/reduced graphene oxide as anode material for lithium-ion batteries

• Facile, green and large scale synthesis method.
• CoMoO4 nanorods possess small diameter (about 40∼60 nm in width and 1.5∼2 μm in length) and uniformly distributed on reduced graphene oxide.
• CoMoO4 nanorods/reduced graphene oxide composite delivered high initial discharge capacity (1496 mA h g−1 at a current density of 100 mA g−1), and good cycling (628 mA h g−1 after 100 cycles) and rate performance (a reversible capacity of 372 mA h g−1 at the rate of 5 A g−1).

CoMoO4 nanorods with small diameter (about 40∼60 nm in width and 1.5∼2 μm in length) uniformly distributed on reduced graphene oxide (rGO) nanosheets were synthesized via a facile, green wet chemical method. The as-prepared CoMoO4/rGO composite was studied as anode material for lithium-ion batteries. It delivered an initial discharge capacity of 1496 mA h g−1 at a current density of 100 mA g−1, and good cycling (628 mA h g−1 after 100 cycles) and rate performance (a reversible capacity of 372 mA h g−1 at the rate of 5 A g−1). The excellent electrochemical performance can be attributed to the small diameter of the synthesized CoMoO4 nanorods and the presence of rGO nanosheets, making it a promising candidate for next generation anode material of rechargeable lithium ion batteries.
