Optimize the Dispersion of Battery Materials for a Better Laser Diffraction Particle Size Test

Accurate measurement of lithium iron phosphate (LFP) particle size distribution (PSD) is crucial for optimizing battery performance. This study explores the challenges associated with LFP PSD measurement and proposes a tailored solution through pre-dispersion with ultrasonication.

The optimal pre-dispersion settings, identified through a series of tests, involve ultrasonication at 510W for 1 minute. This approach yields a stable PSD with a D100 value of 10.27 μm and exhibits excellent repeatability, complying with ISO 13320 standards. This approach empowers researchers and engineers to optimize LFP battery performance and accelerate the development of sustainable energy solutions.
