Effect of Heat Treatment Technology on Property of Sodium-Sulfur Battery Cathode Carbon Felt

Article Preview

Abstract:

The heat treatment technology of PAN based carbon felt used for sodium-sulfur battery was studied. The influence of different heat treatment technologies on element content of felt and the microstructure of graphitized felt was investigated by the element analysis, Raman spectroscopy. The relationship between element content and resistivity of felt was discussed. Results showed that the oxidation time was shorter, the oxygen content of the stabilized felt was lower, which resulted in higher carbon content of graphitized felt. Thus the higher degree of graphitization produced the more regular structure and the lower resistivity of the felt.
