摘要 采用液态混合、固相反应相结合制备了锂离子电池正极材料Li2FeSiO4/C,研究了合成温度对材料结构和电化学性能的影响。利用X射线衍射(XRD)、扫描电镜(SEM)和恒流充放电,电化学交流阻抗(EIS)等测试方法对材料的结构、表观形貌及电化学性能进行表征。考察焙烧温度对Li2FeSiO4/C材料合成及其性能的影响。结果表明:650℃的样品在25℃以0.1C进行恒流充放电,其首次放电容量为103.31 mAh/g,10次循环后的比容量为81.35 mAh/g。 Li2FeSiO4/C was synthesized at different temperature by liquid and solid state reaction. The prepared samples were characterized by XRD, SEM, galvanostatic charge-discharge test and electrochemical impedance spectrum(EIS) . The influences of irrational temperature on the synthesis and properties of Li2FeSiO4/C materials were examined. Electrochemical tests show that the first specific discharge capacity of the Li2FeSiO4/C synthesized at 650 ℃ is 103. 31 mAh/g at 0. 1C,and the discharge capacity remains 81. 35 mAh/g after 10 charge and discharge cycles at 25 ℃ .
