Synthesis of lithium-ion battery cathode material LiFe_(0.95)Mn_(0.05)PO_4/C using FeCl_3 etching waste as iron source

摘要

In this paper, LiFe_(0.95)Mn_(0.05)PO_4/C was prepared by using simulated FeCl_3 etching waste as iron source for lithium-ion battery cathode materials. The structural and morphological properties of the samples were characterized by X-ray powder diffraction (XRD) and Scanning electron microscopy (SEM). The electrochemical performances of the sample were also investigated with charge and discharge test. The achieved results indicate that product obtained was confirmed to be LiFe_(0.95)Mn_(0.05)PO_4 and has the advantage of high purity, small size and good electrochemical performance.
