摘要
橄榄石结构的LiCoPO4具很高的能量密度、比能量,以及高达4.8V(Li/Li+)的电压平台,有望成为高电压、高容量的新一代锂离子电池正极材料。本文主要介绍了这种高压锂离子正极材料的晶体结构和反应机理,制备该材料的主要方法,以及针对这种材料电导率低的缺陷,国内外所做的改性研究,并对该材料的未来发展进行了展望。
Due to high energy density,specific capacity and a high voltage platform of 4.8V(Li/Li+),olivine structure LiCoPO4 has a potential to be a new type of cathode material for Li-ion battery with high voltage and capacity.In the paper,the crystal structure,intercalation mechanism of cathode material LiCoPO4 was reviewed,and the preparation methods,the research progress of modification was summarized.The development prospect of the material was forecast.
