Abstract
Methods and apparatus relate to preparing particles for use as electrode material in batteries. Wet attrition milling provides the particles sized as desired. Pre-milling with a jet mill, for example, may occur prior to the wet attrition milling. Further, adding a soluble carbon-residue-forming material to a suspension before and/or after the wet attrition milling can facilitate the wet attrition milling and/or enable in-line coating via procedures causing precipitation of the carbon-residue-forming material onto the particles that are sized.
