| 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. |
