Anode material SnS was synthesized by ethanol and ammonia as solvent,respectively.The samples were studied by XRD,SEM,electrochemical impedance spectroscopy,cyclic vohammetry and galvanostatic charge-discharge.The pure orthorhombie SnS crystal was obtained by ethanol as solvent.its particle size was smaller and more uniform compared with the one by ammonia as solvent.When SnS syrnthesized by ethanol as solvent charge-discharge at 0.1 C,0.5 C,0.8 C and 1.0 C,the lithium deintercalation specific capadty fading was the slowest at 0.5 C,the specific capacity was 243.2 mAh/g at the 20th cycle.
