dc.description.abstract | The principal drawback of lithium-sulfur batteries is the dissolution of long-chain lithium polysulfides into the electrolyte, which limits cycling performance. To overcome this problem, we focused on the development of a novel cathode as well as anode material and designed Nafion-coated NiCrAl/S as a cathode and lithium powder as an anode. Nafion-coated NiCrAl/S cathode was synthesized using a two-step dip-coating technique. The lithium-powder anode was used instead of a lithium-foil anode to prohibit dendrite growth and to improve on the electrochemical behaviors. The cells showed an initial discharge capacity of about 900 mAg(-1) and a final discharge capacity of 772 mAg(-1) after 100 cycles at 0.1 C-rate. Scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) demonstrate that using the Nafion-coated NiCrAl/S cathode can suppress the dissolution of long-chain lithium polysulfides. | - |
