Abstract

The electrochemical performance of NCF-sulfur cathode,with different NCF contents,was investigated by constant current discharge,cyclic voltammetry and AC impedance methods.The morphologies of the cathodes were observed using scanning electron microscopy.The results indicate that the cycle life and rate capability of NCF-sulfur cathode increased.Better performance of sulfur cathode was obtained by 3% and 5% NCF conductive addition.When the current density was 0.4 mA/cm2,the 3%NCF-sulfur cathode had an initial capacity of 880 mAh/g and a reversible capacity of 630 mAh/g after 20 cycles.
