中文摘要	Carbon-coated macroporous SnP2O7 characterized by SEM, XRD, and FTIR was prepared by facile synthesis, aiming to take advantages of macroporous Structure and carbon coating. The performances as anode materials for Li-ion battery were investigated by galvanostatic discharge/charge and electrochemical impedance spectroscopy (EIS). The charge/discharge experiments showed that the cycle performances of carbon-coated macroporous SnP2O7 electrode were largely enhanced as compared to uncoated macroporous SnP2O7 electrode, which delivered 392.3 and 122.8 mAh g(-1) at the 20th cycle, respectively. The EIS test exhibited that the charge-transfer resistance of carbon-coated macroporous SnP2O7 was smaller than that of uncoated macroporous SnP2O7. The results showed that carbon-coated macroporous SnP2O7 might have potential application as anode materials for Li-ion battery.
