磷酸铁锂的液相合成及改性研究进展 罗传喜1,宋慧宇1,廖世军1 (1.华南理工大学化学与化工学院,广州,510641) 摘要:橄榄石结构的LiFePO_4以其高比容量,低成本,环境友好,热稳定性良好等优点而成为一类最具发展前景的锂离子电池正极材料,但电导率和离子扩散率低是制约其在动力电池领域广泛应用的主要障碍.从材料制备和改性等方面综述了近年来国内外利用液相法合成LiFePO_4以及掺杂改性的研究状况,比较了水热法,共沉淀法,溶胶-凝胶法及掺杂对材料性能的影响,认为合成材料的形貌和粒径以及导电剂或少量金属离子的掺杂是提高LiFePO_4电导率的有效方法,指出今后的重点方向是合成工艺的改进和理论的继续深入研究. 关键词:磷酸铁锂(LiFePO_4)液相合成电化学性能改性; lithium iron phosphate; wet-chemical synthesis......
