| Keyword | |||
| Abstract | The lithium iron phosphate (LiFePO4) was the cathode materials of lithium ion secondary battery. In order to make the electrical capacity of lithium iron phosphate close to the theoretical value, and increase the battery cycle life. This study added four kinds of different particle size conductive black carbon into LiFePO4, to form a electrode plates and assembled into a battery for increase the capacitance and battery cycle life. The crystal structure and lattice constant of LiFePO4 and conductive carbon black powder was proceed by the X-ray diffraction analysis. The field mission scanning electron microscope was used for observe the shape of LiFePO4 and conductive carbon black powder. The specific surface area of the carbon black was analysis by a specific surface area analyzer. The battery performance test, including the constant current charge-discharge test and the cycle life test was performed. Experiment results show the carbon black with large surface area and better conductivity added into LiFePO4 increased the performance of lithium iron phosphate, extend the capacity and battery cycle life. |
