“…For doping modification, most common single-element doping techniques have been reported, and even synergistic modification by the co-doping of multiple elements has been applied. Due to the complexity of the doping mechanism, many types of cation doping, such as with Mg 2+ , Nb 3+ , Co 2+ , Ti 4+ , and V 5+ , and anion doping, such as with F − , Cl − , etc., have not been fully understood [22][23][24][25][26][27].…”

Lithium iron phosphate (LiFePO4, LFP), an olivine–type cathode material, represents a highly suitable cathode option for lithium–ion batteries that is widely applied in electric vehicles and renewable energy storage systems. This work employed the ball milling technique to synthesize LiFePO4/carbon (LFP/C) composites and investigated the effects of various doping elements, including F, Mn, Nb, and Mg, on the electrochemical behavior of LFP/C composite cathodes. Our comprehensive work indicates that optimized F doping could improve the discharge capacity of the LFP/C composites at high rates, achieving 113.7 mAh g−1 at 10 C. Rational Nb doping boosted the cycling stability and improved the capacity retention rate (above 96.1% after 100 cycles at 0.2 C). The designed Mn doping escalated the discharge capacity of the LFP/C composite under a low temperature of −15 °C (101.2 mAh g−1 at 0.2 C). By optimizing the doping elements and levels, the role of doping as a modification method on the diverse properties of LFP/C cathode materials was effectively explored.

“…Xia et al [22] prepared large-scale LiFePO 4 microspheres with a three-dimensional (3D) porous microstructure and these micro/nano-structured LiFePO 4 microspheres have a high tap density, which show excellent rate capability and cycle stability as electrodes. In addition, as one of the most widely used electrode materials of lithium-ion batteries (LIBs) for electric vehicles, LiFePO 4 cathode materials possess many excellent properties, including excellent safety [1][2][3][4][22][23][24][25][26][27][28]. However, the poor discharge capacity at relative lower temperatures (below −20 • C) hinders its practical applications in special environment or regions.…”

“…To date, a number of synthesized methods, such as solid-state techniques [23], hydrothermal synthesis [24], co-precipitation [25], sol-gel reaction [26], as well as other methods with improved electrochemical properties [27,28], have been developed to prepare nano-sized LiFePO 4 particles. As a typical surfactant, OA is used as surfactant and template in solvothermal synthesis of LiFePO 4 cathode materials.…”

As an electrode material, LiFePO4 has been extensively studied in the field of energy conversion and storage due to its inexpensive cost and excellent safety, as well as good cycling stability. However, it remains a challenge to obtain LiFePO4 electrode materials with acceptable discharge capacity at low temperature. Here, micro/nano-structured LiFePO4 electrode materials with grape-like morphology were fabricated via a facile solvothermal approach using ethanol and OA as the co-solvent, the surfactant as well as the carbon source. The structure and electrochemical properties of the LiFePO4 material were investigated with x-ray diffraction (XRD), field emission scanning electron microscopy (SEM), cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS), and the formation mechanism of the self-assembled micro/nano-structured LiFePO4 was discussed as well. The micro/nano-structured LiFePO4 electrode materials exhibited a high discharge capacity (142 mAh·g−1) at a low temperature of 0 °C, and retained 102 mAh·g−1 when the temperature was decreased to −20 °C. This investigation can provide a reference for the design of micro/nano-structured electrode materials with improvement of the electrochemical performance at low temperature.

Significant attention has focused on olivine‐structured LiFePO4 (LFP) as a promising cathode active material (CAM) for lithium‐ion batteries. This iron‐based compound offers advantages over commonly used Co and Ni due to its lower toxicity abundance, and cost‐effectiveness. Despite its current commercial use in energy storage technology, there remains a need for cost‐effective production methods to create electrochemically active LiFePO4. Consequently, there is ongoing interest in developing innovative approaches for LiFePO4 production. While LFP batteries exhibit significant thermal stability, cycling performance, and environmental benefits, their growing adoption has increased battery disposal rates. Improper disposal practices for waste LFP batteries result in environmental degradation and the depletion of valuable resources. This review comprehensively examines diverse synthesis approaches for generating LFP powders, encompassing conventional methodologies alongside novel procedures. Furthermore, it conducts an in‐depth assessment of the methodologies employed in recycling waste LFP batteries. Moreover, it emphasizes the importance of LFP cathode recycling and investigates pretreatment techniques to enhance understanding. Additionally, it provides valuable insights into the recycling process of used LFP batteries, aiming to raise awareness regarding the market for retired LFP batteries and advocate for the enduring sustainability of lithium‐ion batteries.
