Electrochemical Performance Study of LiFePO₄ Cathode Material with Different Carbon Coating Contents

Abstract:

The co-precipitation method synthesized LiFePO₄/C composite cathode material combined with high temperature carbonization, the amount of carbon source added was characterized by XRD, SEM and other physical tests, as well as its electrochemical properties. The results show that the amount of carbon-coated has a certain influence on the properties of the materials. Which carbon-coated contents of 60% from the first discharge the specific capacity can reach 150.77mAh/g in the discharge rate of 0.1C, and has a retention rate of 90.74% in the discharge of 1C, which has to meet the needs of practical application .
