First Phosphate Corp. 's pilot project to transform its high purity phosphate concentrate into battery-grade purified phosphoric acid (“PPA”) for the lithium iron phosphate (LFP) battery industry has been successful.
One of its precursors is phosphoric acid. Lithium iron phosphate (LFP) batteries are one of the earliest types of lithium-ion battery. LFP cathode material has theoretical capacity of 170 mAh/g, and relatively low energy density limited by the voltage (3.4V) comparing with energy density of the ternary lithium battery.
Phosphoric acid is produced two processes: wet process and thermal process. The majority of the of the phosphoric acid is produced by the wet process of which approximately 90% is converted to fertilizers . There are two main processes in the wet process route, and these are dihydrate (DH) and hemihydrate (HH) processes.
The PG formed is either the dihydrate form (CaSO 4.2H 2 O) or the hemihydrate form (CaSO 4.0.5H 2 O). As such, the common technologies in the production of wet process phosphoric acid are the dihydrate technology or the hemihydrate technology .
The demand for phosphorus in the battery industry has seen a surge recently with each producer looking for means of improving battery performance. One such material is the lithium iron phosphate (LFP) used in battery cathodes. One of its precursors is phosphoric acid.
The process is known as “thermal” when the raw material is elemental phosphorus. This process has been abandoned because of the amount of energy which is needed. The processes that use phosphated minerals which are decomposed with an acid, are known as “wet processes” and they are the only economic alternative way to produce phosphoric acid.
