The Battery Experts video series with Anthony Chalou from Anton Paar explores the crucial aspects of particle size and shape in electrode materials for lithium-ion batteries. In this video, Anthony explains how these characteristics impact lithium ion diffusion and the homogeneity of the battery slurry.
The video covers two primary technologies for measuring particle size: laser diffraction, suitable for particles between 40 nanometers and 2.5 millimeters, and dynamic light scattering (DLS), ideal for particles in the 0.3 nanometers to 10 microns range. For typical electrode materials, laser diffraction in wet mode is preferred.
Anthony details the process of selecting analysis modes, performing background measurements, and obtaining size distributions to calculate the median particle size.
DLS is employed for smaller particles, such as electrode additives. Anthony explains the setup, including cuvette selection and material type configuration, demonstrating how to achieve mono-modal particle size distribution for optimal battery manufacturing.
The video also highlights the importance of particle shape, measured using dynamic image analysis. This technique offers three dispersion options and covers a wide range of particle sizes from 0.8 microns to 8 millimeters.
The video guides viewers through the setup, including magnification mode selection and automatic stop criteria for data acquisition.
Understanding particle size distribution and shape is vital for enhancing power and energy density in lithium-ion batteries, and ensuring the quality and consistency of the battery slurry during manufacturing.
