Guangdong Brunp Recycling Technology Co., Ltd.

Precursor (iron phosphate) for lithium iron phosphate cathode materials. Brunp uses an alkaline precipitation process with breakthrough improvements in raw materials and process route, or prepares battery-grade iron phosphate from the phosphorus-iron residue left after lithium extraction from spent LFP powder. It features high specific surface area, low sulfur, high tap density and low cost, and serves the manufacture of high-compaction lithium iron phosphate cathodes.
