Effect of Sintering Time and Heating rate on the Structure of LiFePO4/C Prepared by Electrospinning

摘要：

　　The electrospinning combined with the sintering process were used to prepare carbon-coated lithium iron phosphates (LiFePO4/C) cathode materials for lithium ion batteries (LIB).In sintering process,different procedures were used to synthesize the LiFePO4/C composite materials.The effect of the sintering time and heating rate on the structure,surface morphology and carbon content of LiFePO4/C composite materials were investigated by wide angel X-ray diffraction (WXRD),scanning electron microscope (SEM),and elemental analysis (EA) techniques.It has better structure when the sintering process is as follows:heating rate is 2 ℃ min-1 and pre-oxidized time is 3h at 280 ℃ and carbonized time is 8h at 700 ℃.
