You have full access to this open access article Lithium iron phosphate (LiFePO 4, LFP) has long been a key player in the lithium battery industry for its exceptional stability, safety, and cost-effectiveness as a cathode material.
It is worth noting that the stability of phosphate structure particularly strong P O bond imparts higher thermal stability as well as longer lifecycle to the LFP batteries making them suitable for stationary energy storage systems or a specific kind of EVs with defined safety requirements.
LFP batteries are more sustainable in the long run because they have a longer lifespan and consist of less hazardous chemistries that are easily managed and cost-effective at their end of life . The recyclability of LFP batteries is superior to that of NMC batteries due to the stability of materials used such as iron and phosphate.
The present experiment employed lithium iron phosphate pouch cells featuring a nominal capacity of 30 Ah, procured from a recycling facility situated in Hefei City (electrochemical assessments disclosed an effective capacity amounting to only 70 % of the initial capacity).
The environmental effects of lithium-ion batteries are determined by their materials, energy consumed during production, and how they are disposed at end-of-life. LFP batteries have a lesser environmental impact than NMCs because of less hazardous materials used and lower energy consumption during production .
