| Abstract: | The polarization behaviors of Fe, Co, Ni, Pb and graphite in 1.3 mol ·L~(-1)Na_2S_(4)aqueous solution were investigated by the method of steady-state polarization in an ordinary 3-electrode glass cell. The exchange current densities of these materials were also determined . Polyacrylonitrile(PAN)-based carbon felt and nickelfoamor carbon felt with Ni or Co coat were used as positive and negative electrode materials for the polysulfide/bromine battery(PSB). The energy efficiency and cycle performance of PSB were determinedat room temperature. The results showed that PAN-based carbon felt with Ni or Co coat and nickel foam are the suitable negative electrode materials for PSB. The energy efficiency of PSB isabout 80 % (at a charge-discharge current density of30 mA/cm~2), and the cycle performance is perfect. |
