摘要
介绍了锂离子电池正极材料LiFePO4的结构特征和电化学过程。评述了近年来制备LiFePO4的各种方法,包括固相法,液相法(水热法、液相共沉淀法等),微波法等。橄榄石型磷酸铁锂(LiFePO4)理论比容量为170 mA.h/g,电压为3.5V(vs.Li/Li+),环境友好,成本低廉,热稳定性较好,可望成为锂离子蓄电池的新型正极材料。
Structural characteristics and electrochemical processing of LiFePO4 for lithium - ion batteries cathode material were introduced, and preparation of LiFePO4 developed in recent years were reviewed including solid - phase method, liquid -phase method （hydrothcrmal method, liquid- state co -precipitation method and so on） and microwave method. Olivine - type lithium iron phosphate was cheap, non - toxic and friendly to environment with high theoretical capacity （ 170 mA · h/g）, voltage of 3.5 V （ vs. Li/Li^＋ ） and good stability both at room temperature and higher temperature, which could be developed as a potential cathode material for lithium - ion batteries.
