车用动力电池材料的研究分析

Research and Analysis of Li-ion Power Battery Material

从材料层面对车用动力电池当前和未来的主流技术路线进行了比较与分析。针对正极材料,基于对三元正极和磷酸铁锂正极材料的性能和市场应用情况的比较,预测未来正极材料的发展方向。针对负极材料,由于传统的碳类负极性能提升空间十分有限,研发高容量类硅负极正在成为各大电池材料和电芯厂商的关注方向。

The current and future mainstream technology roadmap of Li-ion power battery from the material aspects are compared and analyzed. In view of cathode materials, based on comparison of performance and market application of ternary cathode and lithium iron phosphate, the future develop- ment and application of cathode materials are predicted. For anode materials, due to a very limited en- hancement of carbon materials, development of high-capacity silicon anode are becoming more and more important and necessary.
