| titleOfInvention | Preparation method of nano-silver composite lithium iron phosphate cathode material |
| abstract | The invention discloses a preparation method of a nano-silver composite lithium iron phosphate anode material. And then washing with a water-alcohol mixed solution to remove ascorbic acid or carbonizing the ascorbic acid by high-temperature treatment at 300-700 ℃ in a protective atmosphere to obtain the nano-silver composite lithium iron phosphate anode material. After the modification by the method, the conductivity of the lithium iron phosphate positive electrode material is obviously improved, and the specific capacity, the cycling stability and the rate capability are obviously improved. The initial discharge specific capacity of the nano-silver modified lithium iron phosphate can reach 163mAh/g, and the capacity is not attenuated after 80 cycles. The specific capacity reaches 95mAh/g under the 5C multiplying power. The method adopted by the invention is simple, easy to operate, easy for industrial production, relatively low in energy consumption and less in environmental pollution. |
