Application of Different Sputtering Coating Sample Preparation Methods in Observing the Morphology of LiFePO4 Materials
This experiment compared the microstructure and particle size analysis of LiFePO4 material using three different sputtering coating prepa-ration methods using cold field emission scanning electron microscopy.The results showed that samples prepared by sputtering gold coating,sputte-ring platinum coating,and non sputtering coating can be effectively analyzed for material particle size distribution through scanning electron mi-croscopy.Observing the samples of sputtering coated platinum and non sputtering coated can clearly observe the microstructure of LiFePO4 materi-al.The sample preparation method of non sputtering coating can effectively reduce the cost of personnel and consumables;Observing the samples of sputtered gold coating,due to the large size of gold particles,the microscopic details of the surface of LiFePO4 are largely masked,resulting in distorted microscopic morphology observed.The results show that when observing LiFePO4 cathode materials using cold field scanning electron mi-croscopy,the microscopic details of the material surface can be clearly observed by non sputtering coating preparation,while effectively reducing personnel and equipment costs and improving the efficiency of material morphology observation and particle size analysis.
