Surface| Zusammenfassung: | LiFePO4, LiCoPO4, LiMnPO4, LiFe1-xCrxPO4, LiFe1-xMnxPO4 nanocrystals have been synthesized by deposition in a LiNO3 melt (400-450 0C). The phase and chemical composition, microstructure, morphology of the powder samples obtained of phosphates and their nanocomposites with carbon have been studied by X-ray phase analysis, emission spectrum analysis, electron microscopy. According to cyclic voltammetry data and galvanostatic discharging curves, the electrode process at the samples synthesized in the melt is distinguished by reversibility, low capacity loss and good cycling kinetics. For substituted phosphate, the peaks on cyclic voltammograms are much larger than for LiFePO4. |
