英文摘要：

Cu Fe2O4 was prepared by the hydrothermal method,and its the electrochemical characteristics were investigated. SEM test results showed that the material was micrometer sheet structure with good distribution.XRD analysis showed that the crystals with crystal surface of [220],[311],[400],[422],[511],[440]were identical to the cube standard spinel structure of Cu Fe2O4 spectra,indicating the the obtained product has a standard spinel crystal. The charge and discharge curves were detected. The results showed that the first charge and discharge capacities were 484. 2 m Ah·g- 1and 512. 5 m Ah·g- 1,357. 1 m Ah·g- 1and 373. 5 m Ah·g- 1for the 5 th cycle. 294 m Ah·g- 1and 305. 4 m Ah·g- 1,274 m Ah·g- 1and 282. 2 m Ah·g- 1,260. 3 m Ah·g- 1and 269. 2 m Ah · g- 1,228. 7 m Ah · g- 1and 233. 3 m Ah · g- 1for the 10 th,30 th,50 th,70 th cycle,respectively.
