Abstract

Abstract Li-ion secondary battery is highly recommended as a power source to highly advanced battery electric vehicles. Among various types, the lithium nickel cobalt aluminum oxide (NCA) battery is considered suitable for high energy and power application. In this study, the NCA cathode material LiNi0.89Co0.08Al0.03O2 was produced via the oxalate co-precipitation technique to reduce the overall production cost and process complexity. Oxalic acid and a small amount of sodium hydroxide were used as the precipitant and pH regulator, respectively. Homogenous and loose metal oxalate precipitate formation was confirmed by X-ray diffraction (XRD), scanning electron microscopy, and Fourier-transform infrared spectroscopy analysis. XRD patterns of the as-obtained micron-sized NCA showed a well-layered hexagonal structure. The electrochemical properties of the cathode in the full cell were thoroughly examined. The specific discharge capacity of the as-obtained NCA in NCA/LiPF6/graphite at a current rate of 20 mA/g was 142 mAh/g. The as-prepared NCA sample had capacity retention of 80% after being charged and discharged at 0.1 A/g for 101 cycles. Scaling up of NCA production process to 2 kg per batch was conducted and evaluation of NCA product quality was performed by material characterization. Based on the overall results and considering the overall process, such an approach is expected to be developed and improved for future large-scale production purposes.

制备高容量NCA/石墨二次电池用富镍lini0.89 co0.08 al0.030 o2正极材料

摘要：强烈建议将锂离子二次电池作为高度先进的电池电动汽车的电源。在各种类型中，锂镍钴氧化铝（NCA）电池被认为适合高能量和高功率应用。在本研究中，通过草酸盐共沉淀技术生产了NCA正极材料LiNi0.89Co0.08Al0.03O2，以降低整体生产成本和工艺复杂性。草酸和少量氢氧化钠分别用作沉淀剂和pH调节剂。通过X射线衍射（XRD）、扫描电子显微镜和傅里叶变换红外光谱分析证实了均匀和松散的金属草酸盐沉淀的形成。所获得的微米级NCA的XRD图谱显示出良好的层状六边形结构。对全电池中阴极的电化学性能进行了彻底的检查。NCA/LiPF6/石墨中所获得的NCA在20的电流速率下的比放电容量 mA/g为142 mAh/g。所制备的NCA样品在0.1下充电和放电后具有80%的容量保持率 A/g，循环101次。NCA生产流程扩大到2 kg每批进行，并通过材料表征进行NCA产品质量的评估。基于整体结果并考虑整体过程，预计将为未来的大规模生产目的开发和改进这种方法。
