UNION PROCESS: Phosphate Precursor Process

This Akron-based equipment maker has developed a two-phase process for grinding and dispersing the phosphate precursor required for lithium-ion batteries. The first phase uses the company’s S-series attritors to grind and disperse the coarse precursor powder to a 1-3 µm particle size range. The second phase runs through the company’s DMQ series horizontal media mills, dispersing the finished material to a primary particle size range of 200-300 nm.

“Thorough testing of this two-phase method of processing lithium-ion phosphate precursor has shown a high level of repeatability,” said Arno Szegvari, CEO. “As transportation choices become more eco-friendly, we are pleased that we can contribute to the continuing expansion of green technology.”
