在本研究中，我们研究了使用微波处理来制备锂二次电池正极材料LiFePO 4。通过X射线衍射、扫描电镜和电化学性能对样品进行了表征。通过添加铁粉或碳粉，采用微波法成功制备了橄榄石相LiFePO 4。在60 oC下，添加碳粉制备的LiFePO 4的首次放电容量为134 mAh/g。
In the present study, we examined the use of microwave processing to prepare LiFePO4 cathode materials for lithium secondary batteries. Prepared samples were characterized by X-ray diffraction, SEM photographs, and electrochemical properties. Olivine-phase LiFePO4 was successfully prepared by microwave processing with the addition of iron or carbon powder. The initial discharge capacity of the LiFePO4 prepared with the addition of carbon powder was 134 mAh/g at 60 oC.
