Evaluation of particle size of positive electrode active material
Introducing examples of measurement cases for important management items in the production of lithium-ion batteries and all-solid-state batteries!
We would like to introduce a case of particle size measurement of cathode active materials using laser diffraction conducted by our company. In air or liquid, laser light is irradiated onto the particles, and the angular dependence of the intensity of the light scattered by the particles is measured. By measuring the angular dependence of the scattered light intensity, the particle size distribution (particle size distribution) is calculated from the data. Using commercially available reagents as samples, measurements were conducted in a dry state without dispersing in a solvent. The particle size measurement results for NMC oxides showed a monodisperse state with particle sizes below several tens of micrometers, and the median diameter was calculated to be 12 micrometers.
