摘    要:采用湿法机械活化混料、喷雾干燥、固相烧结法制备了磷酸铁锂。实验结果表明, 在合适的球料比、液固比下, 经过3 h机械活化的物料烧结后, 产品的0.2C首次放电容量为151.8 mAh/g, 30次循环衰减为0.80%, 明显优于干法混料产品的电性能。

关 键 词:锂离子电池  正极材料  磷酸铁锂  均一性  机械活化  固相烧结  电性能

Abstract:Lithium iron phosphate was prepared with wet mixture through mechanical activation,spray drying and solid-state sintering processes.Test results showed that with proper ball to powder weight ratio and liquid-solid ratio,the material being mechanically activated for 3 hours and subjected to sintering process,resulted in a product with the first discharge capacity of 151.8 mAh/g at 0.2C,with an attenuation rate of 0.80% after 30 cycles,which is obviously better than the product obtained with dry mixture in terms of electrical properties.
Keywords:lithium ion battery  anode material  lithium iron phosphate  homogeneity  mechanic activation  solid state sintering  electrical properties
