摘要
锂离子电池主要由正极材料、负极材料和电解质组成。在众多的正极材料中,磷酸铁锂(LiFe-PO_(4))因价格低廉、原料易得、循环性能好和环境友好等优点走进了大众的视野。然而,其低温性能差、电导率低等缺点仍制约着LiFePO_(4)的发展。因此,本文重点综述了LiFePO_(4)材料的制备方法及改性研究,对其未来发展方向进行了展望。
Lithium ion battery are mainly composed of cathode materials,anode materials,and electrolytes.Among various cathode materials,lithium iron phosphate(LiFePO_(4))has attracted significant attention due to its low price,easy availability of raw materials,good recycling performance,and environmentally friendly advantages.However,its poor low temperature performance and low conductivity still restrict the development of LiFePO_(4).Therefore,this paper focuses on the preparation methods and modification research of LiFePO_(4) materials,and prospects its future development direction.
