Abstract. This study aims to enhance the electrochemical properties of solid-state lithium-ion batteries by modifying the cathode material, LiFePO 4 (LFP), via fluorene addition and in-situ polymerisation. The first modification process involves creating a shell structure (the film thickness of 10 nm) around each LFP particle and establishing
How the LFP Battery Works LFP batteries use lithium iron phosphate (LiFePO4) as the cathode material alongside a graphite carbon electrode with a metallic backing as the anode. Unlike many cathode materials, LFP is a polyanion compound composed of more than one negatively charged element. Its atoms are arranged in a crystalline structure forming a []
A battery cell with an NMC cathode has a nominal voltage of 3.7V, and the energy density range is between 150 to 300 Wh/kg. On the other hand, LFP is at 3.0-3.2V nominal voltage, and its energy density
Since the full name is a bit of a mouthful, they''re commonly reviated to LFP batteries (the "F" is from its scientific name: Lithium ferrophosphate) or LiFePO4. They''re a particular type of lithium-ion batteries commonly used in everything from EVs to home powerbanks to cell phones .

In short: The LFP battery or G/LFP battery. The cathode material in LFP batteries is Lithium Iron Phosphate. G/LFP batteries have moderate to long life span, but a lower energy density than NMC batteries but offers a slight safety advantage to the G/NMC chemistry. This is due to the chemical structure of LFP which hinders the release of oxygen.

LFP-based batteries do not require the critical raw materials nickel, manganese and cobalt and are therefore not subject to the high price fluctuations of cobalt and nickel.
