| 英文摘要 | Aipo(4) was used to the surface modification of limn2o4 by chemical deposition method to improve the cycling stability of limn2o4 at ambient and elevated temperature. the uncoated and aipo(4)-coated limn2o4 materials were characterized by x-ray diffraction (xrd), transmission electron rnicroscopy (tem) and electrochemical test. while the uncoated limn2o4 showed 17.9% and 32.9% capacity loss in 50 cycles at 30 degrees c and 55 degrees c, respectively, the aipo(4)-coated limn2o4 only exhibited the capacity loss of 2.6% and 7.6% at 30 degrees c and 55 degrees c, respectively. the dq/dv versus potential plots at 55 degrees c revealed that the improvement in cycling performance of the coated-limn2o4 electrode is attributed to the stabilization of the spinel structure by the presence of alpo4 on the surface of limn2o4.
