This article explores the determination of phosphorus and iron content in battery materials lithium iron phosphate products using the glass fusion bead-X-ray fluorescence spectrometry method.After applying the theoretical alpha coefficient correction,the correlation coefficient of the linear regression equation reaches 0.9996,indicating excellent linearity.The relative standard deviation(RSD)for phosphorus(P)is 0.24％,and for iron(Fe)it is 0.12％.The experiment results demonstrates that this method offers good precision and accuracy,with rapid de-tection and easy operation,making it suitable for the rapid determination of phosphorus and iron content in lithium iron phosphate products.
