摘要
锂离子电池具有能量密度大、循环性能好、电压平台高等优点,是当前国内外动力电池领域的研究热点。而正极材料是锂离子电池性能提高的关键所在,其中镍系正极材料是一种极具希望的下一代锂离子正极材料,相对于传统的LiCoO_2正极材料,其具有比容量高、价格低,原料来源丰富等优点。本文介绍了镍钴锰酸锂正极材料的结构及电化学特征,并对其发展前景进行了展望。
The lithium ion batteries possess the advantages of good cycling performances, large energy density, high voltage plateau, and so on, which have become the current domestic and international research hotspot in power battery field. The cathode material plays an important role in improving the performance of lithium ion batteries. Lithium nickel- based oxide is a kind of promising cathode material to power next generation of lithium ion batteries. Compares to commercial LiCoO2, it has advantages on specific capacity, price and abundant resources. The structure and electrochemical characteristics of LiNixCo1-x-yMnyO2 cathode material were introduced. The development of NCM cathode material was also prospected.
