阐述了锂离子电池正极材料钴酸锂和负极材料石墨的发展趋势和市场对正负极材料的要求。随着锂离子电池应用范围的拓宽和人们对锂离子电池高电压、高比能等性能的要求,锂离子电池的高容量和高安全性受到关注。目前钴酸锂依然是锂离子电池用正极材料的主流,但具有相对高安全、高容量、低成本的正极材料替代产品相继开发,并逐步向市场靠近。碳材料仍然在锂离子电池负极材料中占绝对优势,市场竞争的加剧导致负极材料向高容量、低成本方向转化。

The development status and trends of cathode material LiCoO2 and anode material graphite were summarized in this paper.More and more attentions are being paid on the capacity and safety of Li-ion battery for its wider use and higher performance demands.At present,LiCoO2 cathode material is still playing a leading role in market,but the alternative cathode materials with higher safety,higher specific capacity and lower cost are being developed and tried into practice.Anode material graphite will not be replaced for its good performance for a long period,but its high specific capacity and low cost are needed.
