磷酸铁锂作为一种动力电池的重要正极材料,其产品质量直接影响到电池的性能、寿命及安全性.而在磷酸铁锂质量控制中,磁性金属颗粒作为重要检测项目,其对电池的性能影响较大,本文提出一种清洁度仪湿法测定磷酸铁锂中磁性金属颗粒的检测方法,通过湿法滚动吸附、水洗、醇洗、酸洗等单元操作处理磷酸铁锂试样,尽可能地将磁性金属颗粒裸露,以到达磁性金属颗粒呈现自身的金属光泽,增强检测准确性,再通过清洁度仪处理后,即可完成检测.试验结果表明:该方法能够准确地测定磷酸铁锂中磁性金属颗粒数量及粒径分布,是一种简单、快速、准确的磷酸铁锂中磁性金属颗粒检测方法,为产品质量控制和性能评估提供技术支持.
Detection Method for Cleaning Magnetic Metal Particles in Lithium Iron Phosphate Using Wet Method
Lithium iron phosphate is an important cathode material for power batteries,and Its product quality directly affects the performance,life and safety of the battery.In the quality control of lithium iron phosphate,magnetic metal particles are an important testing item,which affects the performance of the battery.This paper proposes a test method for the wet determination of magnetic metal particles in lithium iron phosphate by cleanliness meter.The lithium iron phosphate samples are processed through wet rolling adsorption,water washing,alcohol washing,pickling and other unit operations to expose the magnetic metal particles as much as possible,so that the magnetic metal particles can show their own metallic luster,enhance the detection accuracy,and then after being processed by the cleanliness meter,the test can be completed.Experimental results show that this method can accurately determine the number and particle size distribution of magnetic metal particles in lithium iron phosphate.It is a simple,fast,and accurate method for detecting magnetic metal particles in lithium iron phosphate,and provides technical support for product quality control and performance evaluation..
