M2P2S6(M=Mn,Ni)with a layered structure was synthesized by solid state method at room temperature. The products were characterized by XRD,SEM,EDS,IR and TG. The Mn2P2S6 powders are accumulated with a large amount of nanospheres with diameters of 40 50 nm and the Ni2P2S6 product is blocky structure made of different sizes particles. M2P2S6(M=Mn,Ni)were used as active anode materials for lithium-ion battery and their electrochemical properties were tested by constant current charge-discharge cycling. The results show that the initial discharge capacity of M2P2S6(M=Mn,Ni) were 800 mAh/g and 911 mAh/g respectively,which means M2P2S6 compounds can be potential anode materials of lithium-ion battery.
