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

CoMoO4 nanorods with small diameter (about 40 similar to 60nm in width and 1.5 similar to 2 mu m 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.
