摘要
使用熔融盐法合成了似球状结构的碳包覆LiFePO_(4)阴极材料。采用X射线衍射(XRD)确证产品结构,扫描电镜(SEM)观察产品形貌,电化学循环测试仪测试其电化学性能。结果表明,熔融盐法制得的LiFePO_(4)颗粒为类球状结构,材料的振实密度有了一定的提升。其50次循环的容量保持率接近100%,表现出了较为优异的电化学性能。
In this study,carbon-coated LiFePO_(4)cathode material with spherical structure was synthesized by molten salt method.Xray diffraction(XRD)was used to confirm the product structure,scanning electron microscope(SEM)was used to observe the product morphology,and the electrochemical cycle tester was used to test its electrochemical performance.The experimental results show that the LiFePO_(4)particles prepared by the molten salt method are spherical structure,the tap density of the material has been improved.The capacity retention rate of 50 cycles is close to 100%,and it shows excellent electrochemical performance.
