Lithium Storage Property of MoS2 with Mechanical Alloying Treatment
MoS2 is a candidate for new generation lithium ion battery anode. In this paper, two groups of materials, pure MoS2 and MoS2/graphite composite, were treated by mechanical alloying (MA). The results showed that MA treatment did not change the phase structure of MoS2, but MA will reduce the particle size of MoS2. For MoS2/graphite composite, MA makes graphite distributing homogeneous on the surface of MoS2. After MA, MoS2 keeps the character of 100% columbic efficiency during charging and discharging process. With the increase in cycle number, capacity of MoS2 decays. MA treatment on MoS2 accelerates the decay of capacity. The addition of graphite in MoS2 reduces the harmful effect of MA treatment on cycling property.
