Abstract
LiFeBO3 cathode material was synthesized by solid-state reaction using LiOH·H2O, H3BO3 and FeC2O4·2H2O as raw materials. Structure, morphology and electrochemical performance were investigated by means of X-ray diffraction (XRD), scanning electron microscopy (SEM) and electrochemical measurements. The results show that the LiFeBO3 material sintered at 750 ℃ had high crystallinity with uniform grain size distribution, and possessed optimal electrochemical performance. The initial discharge capacity of the battery with the cathode material was up to 154.6 mA·h·g-1 at change-dischange rate of 0.1C. When the rate were at 0.2C, 1C and 3C, the sample exhibited initial discharge capacities of 118.3, 93.3 and 51.8 mA·h·g-1, respectively; after 25 cycles, the discharge capacity maintained at 81 mA·h·g-1, indicating excellent stability in electrochemical properties.
