中文摘要	Carbon-coated macroporous Sn/sub 2/P/sub 2/O/sub 7/ 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 SnP/sub 2/O/sub 7/ electrode were largely enhanced as compared to uncoated macroporous SnP/sub 2/O/sub 7/ electrode, which delivered 392.3 and 122.8 mAh g/sup -1/ at the 20th cycle, respectively. The EIS test exhibited that the charge-transfer resistance of carbon-coated macroporous SnP/sub 2/O/sub 7/ was smaller than that of uncoated macroporous SnP/sub 2/O/sub 7/. The results showed that carbon-coated macroporous SnP/sub 2/O/sub 7/ might have potential application as anode materials for Li-ion battery.
