| 摘 要： | 在不同的温度、物质的量比和煅烧时间等条件下,分别制备FePO4正极材料,并进行X射线衍射(XRD)测试、准开路电压(QOCV)和恒流充放电(CCV)等电化学测试.经湿法研磨后,结晶态FePO4的充放电容量有很大提高,有良好循环特性,表明结晶态FePO4可以通过控制颗粒特性提高比容量,可成为低成本环保型锂电池正极材料.

| Abstract: | The crystalline FePO_4 samples as cathode materials were prepared under different conditions with X-ray diffraction(XRD),quasi open circuit voltage(QOCV) and constant current voltammogram(CCV) detects.The charge-discharge capacity of FePO_4 is greatly increased with good cycling performance after wet milling of FePO_4 with carbon in acetone.This shows the possibility of increasing its capacity by controlling the particle properties of FePO_4,which make it to be a low cost and environment benign cathode material for rechargeable lithium batteries. |
