Optimizing Li-ion Battery Efficiency: Particle Size & Zeta Potential

Particle size is a critical to Li-ion battery electrode development and manufacturing because it influences packing density, Li-ion diffusion speed, electrode durability, power and energy storage density, and powder flowability. When electrode particles are dispersed into slurries, the dispersion stability can be investigated with zeta potential measurements. Finally, during battery recycling, particle size and shape of shredded material is relevant for powder processing. The techniques for these measurements will be introduced, and their relevance to the Li-ion battery industry will be discussed with application examples.
