摘要
自锂离子电池被发现以来,对锂离子电池的正极材料的研究也趋于白热化。继LiCoO2之后兴起了一系列可以作为锂离子电池正极的材料。由于稳定性好,安全性能高,绿色环保而且资源比较丰富,LiFePO4和Li3V2(PO4)3成为锂离子正极材料的候选材料之一,也是现在的研究重点。此文章主要对LiFePO4和Li3V2(PO4)3的结构特点,二者复合材料的复合机制以及电化学性能进行论述,并对LiFePO4和Li3V2(PO4)3复合锂离子电池正极材料的应用及发展方向进行说明。
Since the lithium-ion battery is found,the cathode material for lithium-ion battery is getting intense.Rise of the series can be used as a lithium battery cathode material following the LiCoO2.Due to the good stability,high-performance security,environmental protection and resource rich LiFePO4,Li3V2(PO4)3 to become one of the candidate materials for lithium-ion cathode materials,but also the research focus.This passage focuses on the structural characteristics of LiFePO4,Li3V2(PO4)3 both recombination mechanisms and electrochemical properties of the composite are discussed,and LiFePO4,Li3V2(PO4)3 composite cathode materials for lithium-ion battery applications and the development direction described.
