摘　　要：目前钴元素在锂离子电池正极材料中被广泛应用,其对材料循环性能和结构稳定性的提升表现优异。然而因为钴价格高昂、供应链存在风险以及开采受限等因素,降低正极材料中钴的含量甚至实现无钴化是当前的主要研究方向。无钴富镍层状材料成本低、能量密度高,具有一定优势。本文综述了无钴富镍层状正极材料的合成方法和改善性能的手段,有助于研究人员了解该材料的研究进展。Cobalt is widely used in cathode materials of lithium-ion batteries currently,and it performs excellently in improving material cycling performance and structural stability.However,due to the high price of cobalt,risks in the supply chain,and limitations in mining,reducing the content of cobalt in cathode materials and even achieving cobalt-free production is currently a major research direction.Cobalt-free nickel-rich layered materials have two advantages:low cost and high energy density,which make them become cathode materials with great potential.This article reviews the synthesis and methods to improve the performance of cobalt-free and nickel-rich layered cathode materials,which helps researchers understand the advanced progress of these materials.
