Electrospinning is a common method for preparing one-dimensional nanomaterials. In this study, we used polyacrylic acid (PAA) as a template to prepare one-dimensional nanomaterials LiFePO4@C, which is a positive electrode material for lithium-ion batteries, through electrospinning. The structure and properties of the material were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectrometer (FTIR), and other tools. At the same time, the electrochemical properties of LiFePO4@C were 精品文档---下载后可任意编辑evaluated by cyclic voltammetry (CV) and constant current charge-discharge tests.The results of SEM and TEM showed that the prepared...
