摘要
在当前的电池技术中,锂离子电池(LIB)是塑造未来固定存储能源场所的关键。然而,锂离子电池的容量、循环稳定性和高成本仍是研究和开发的挑战。为了克服这些缺点,富镍三元正极材料以其出色的容量成为关键材料。由于具有高能量密度和高容量,它已成为锂离子电池阴极材料的一个重要类别。通过共沉淀技术合成了单晶 LiNi0.88Mn0.02Co0.10O2(NMC-88)和 LiNi0.83Mn0.06Co0.11O2(NMC-83)阴极粉末材料,并对其进行了系统分析。在这些 NMC 中,NMC-88 在 0.1 C 和 0.5 C 条件下的初始放电容量分别高达 216 mAh/g 和 190.7 mAh/g,在 1 C 条件下循环 90 次后的保持率为 70.6%,而 NMC-83 仅为 44.62%。结果表明,与 NMC-83 相比,高富镍 NMC-88 阴极具有良好的放电容量、速率能力和循环性能,以及更好的界面和稳定性。
Systematic electrochemical analysis of high-capacity NMC-88 and NMC-83 cathodes for lithium-ion batteries
Among the current battery technologies, lithium-ion batteries (LIBs) are essential for shaping future energy sites in stationary storage. However, their capacity, cyclic stability, and high cost are still challenging in research and development. To overcome these drawbacks, nickel-rich ternary cathode materials, with their outstanding capacity, have become the linchpin materials. It represents a prominent class of cathode materials for LIBs due to their high energy density and capacity. A powder material exhibiting single-crystalline LiNi0.88Mn0.02Co0.10O2 (NMC-88) and LiNi0.83Mn0.06Co0.11O2 (NMC-83) cathodes was synthesized through the co-precipitation technique and systematically analyzed. Among these NMCs, the electrochemical evaluation of the NMC-88 revealed a high initial discharge capacity of 216 mAh/g and 190.7 mAh/g at 0.1 C and 0.5 C and achieved 70.6% retention after 90 cycles at 1 C, while the NMC-83 attained only 44.62%. The results suggest that the high nickel-rich NMC-88 cathode has good discharge capacity, rate capability, and cyclic performance, with better interface and stability than NMC-83.
