【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。更多还原

【Abstract】 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(hydrothermal 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.更多还原
