Research on the Performance of Positive Electrode Modified with Fluorinated Carbon Based on Silver Coating

In order to address the problem of poor conductivity of fluorocarbon prepared at high temperature, selecting metal materials with good conductivity to be coated on the surface of fluorocarbon can improve the conductivity of the material and thus improve the electrochemical performance of the battery. In this experiment, Ag is co-precipitated on NCM811, a cathode material for lithium-ion batteries, and through a series of performance test experiments, the mechanism of Ag on the electrochemical performance of fluorocarbon is investigated to analyze the influence of Ag coating on the electrochemical performance of fluorocarbon, so as to determine the optimal capping strategy.
