A lithium-iron-phosphate battery, LiFePO4 battery or LFP battery, is a type of lithiumion battery in which lithium-iron-phosphate is the cathode material. LiFePO4 has many advantages over other Li-ion battery designs and older lead-acid, LA batteries. These batteries are lighter in weight, safer to use, have better charge and discharge characteristics, and have a much longer lifespan. The paper presents the results of the hydrometallurgical process of obtaining ferric phosphate from the Jarosite waste sediment, previously leached with water. The solid residue was then treated with HCl under defined conditions in order to convert Fe into a soluble form. After precipitation of Fe(OH)3 and separation of the solid from the liquid phase, Fe(OH)3 was dissolved with H2SO4 to obtain a ferric sulfate solution. By reacting a ferric sulfate solution with phosphoric acid, and after pH correction with NH4OH, a ferric phosphate product was obtained whose quality meets the requirements of the standard for obtaining lithium batteries in relation to the content of Fe, P, Mg, Na, K, Cu, Mn, Co and Cr.
