摘要
橄榄石型的LiFePO_4材料是一种具有良好发展潜力的电动车用锂电池正极材料,现在已经广泛应用于电动汽车领域,多家企业已经生产出以磷酸铁锂电池作为能源的电动汽车。本文应用一种葡萄糖银镜反应方法,制备出具有银包覆的磷酸铁锂材料。葡萄糖在反应过程中既起到碳源的作用,同时也是银镜反应的重要原料。该银包覆磷酸铁锂材料电导率较高,具有很好的大电流放电能力和较高的功率密度,安全性能极佳,非常适合于作为电动汽车用锂电池的正极材料。
The olivine- type LiFePO_4 material is a good development potential of lithium- ion battery cathode materials for electric vehicles.It is widely used in the energy supply of electric vehicles.And many companies have produced the electric vehicles using LiFePO_4 as the cathode material.In this paper,a glucose silver mirror reaction method is used to prepare a kind of silver- coated lithium iron phosphate material.The glucose in the reaction is not just carbon sourse,but important raw material for the silver mirror reaction.The silver coated lithium iron phosphate material has high conductivity,and good high current ability.It has higher power density and safety performance.This is a good cathode material for electric vehicles.
