The reference electrode is based on lithium iron phosphate (LFP) [19], a well-known cathode material used in Li-ion batteries, which can reversibly de/intercalate Li ions: (1) LiFeP O 4 ⇌ Li + sol + e − + FeP O 4
Generally, lithium iron phosphate batteries use lithium iron phosphate as the positive electrode material. Elemental carbon as the negative electrode material are immersed in an organic solvent of lithium hexafluorophosphate. The flow of lithium ions between the positive and negative electrodes is used to generate current.
The sustainable development of lithium iron phosphate (LFP) batteries calls for efficient recycling technologies for spent LFP (SLFP). Even for the advanced direct material regeneration (DMR) method, multiple steps including separation, regeneration, and electrode refabrication processes are still needed.

The lithium iron phosphate battery (LiFePO 4 battery) or LFP battery (lithium ferrophosphate) is a type of lithium-ion battery using lithium iron phosphate (LiFePO 4) as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode.
The lithium-iron phosphate battery or LFP battery is a variant of the lithium-ion battery with a cell voltage of 3.2 V to 3.3 V. In contrast to conventional lithium cobalt(III) oxide (LiCoO2) batteries, the positive electrode consists of lithium iron phosphate (LiFePO4), while the negative electrode is made of graphite with embedded lithium. This type of battery has a lower energy density than
Lithium-ion capacitor (LIC) has activated carbon (AC) as positive electrode (PE) active layer and uses graphite or hard carbon as negative electrode (NE) active materials. 1,2 So LIC was developed to be a high-energy/power density device with long cycle life time and fast charging property, which was considered as a promising avenue to fill the gap of high-energy

These electrodes are typically made of materials capable of hosting Li +, such as lithium cobaltoxide (LiCoO 2; LCO) or lithium iron phosphate (LiFePO 4; LFP), serving as the positive electrode, cathode, and graphite or alloys, serving as the negative electrode, anode.
Lithium iron phosphate battery is a lithium-ion battery that uses lithium iron phosphate (LiFePO4) as the positive electrode material and carbon as the negative electrode material.
