摘要
正极材料作为锂离子电池的关键组成部分,其容量和能量密度对电池整体性能具有重要影响。氟化亚铁(FeF_(2))与钴酸锂(LiCoO_(2))等商用正极材料相比,具有理论比容量高、能量密度大、放电平台稳定以及原料成本较低等优势,是一种极具发展前景的锂离子电池正极材料。本文介绍了FeF_(2)正极材料的优势与储锂机制,重点总结了其在纳米化、碳包覆或金属元素包覆等改性方向的研究进展,并对当前现状进行了分析,展望了该材料未来的研究方向。
As a critical component in lithium-ion batteries,cathode materials are critical to the performance of lithium-ion batteries,influencing both capacity and energy density.Among these,iron fluoride(FeF_(2))stands out due to its high theoretical specific capacity,excellent energy density,stable discharge platform,and low raw material cost,positioning it as a promising alternative to traditional cathodes like LiCoO_(2).This review highlights the advantages of FeF_(2) as a cathode material,examines its lithium storage mechanisms,and summarizes recent advancements in nanosizing and modifications through carbon or metal element coatings.Additionally,this paper assess the current research landscape and propose future directions for developing FeF_(2) cathode materials.
