摘　　要：高镍正极材料因为其高能量密度、长寿命等优势被广泛用作锂离子电池的正极材料,但因其安全性略差导致更高镍的材料在动力电池方面应用受限。介绍了锂离子电池的失效机理及正极材料不稳定的原因,同步总结了国内外高镍正极材料安全性改善的研究进展,指出了高镍正极材料目前面临的挑战及未来发展方向,以期望对高镍正极材料进一步研究与应用提供一定的参考资料。High nickel cathode are widely used as cathode materials for lithium-ion batteries because of their high energy density and long life,but the application of higher nickel materials in EV batteries is limited because of slightly poor safety.The failure mechanism of lithium-ion batteries and the reasons for the instability of cathode are introduced.The research progress of safety improvement of high-nickel cathode at home and abroad is summarized simultaneously.The current challenges and future development direction of high-nickel cathode are pointed out in order to provide some reference materials for further research and application of high-nickel cathode.
