Facts about Iron Phosphate
Iron phosphate is a common chemical with a variety of uses, including as a human nutritional supplement and as an ingredient in fertilizer.
FP at a Glance
Iron Phosphate (FP)
Iron phosphate, with molecular formula FePO4, is a white off-white monoclinic crystalline powder. Its main purpose is to manufacture lithium iron phosphate cathode materials, catalysts and ceramics.
Use of FP
Iron Phosphate is characterized by its high purity, high crystallinity, small primary particles, moderate specific surface area distribution, low impurity content, and stable physical and chemical indicators from batch to batch. These characteristics make it advantageous for synthesizing lithium iron phosphate with high electrical performance.
How do we make FP?
​Irontree uses lithium iron phosphate waste batteries as raw materials for their battery-grade iron phosphate products. They employ patented methods in their battery pre-treatment procedures to obtain high-quality lithium iron phosphate powder.
FP production site
Iron phosphate is a crucial component in the production of LFP batteries, as it determines their characteristics and performance. However, producing high-quality iron phosphate is challenging due to its dust and odor. While there are challenges to producing it in the United States, factories in China have been able to mass-produce it using new technology.
Procuring ferric phosphate from factories outside the U.S. is also viable since its purchase cost accounts for a relatively low proportion of the raw material cost of LFP. Consequently, Irontree can source these materials economically while still qualifying for IRA tax credits.
