    Improving the self-discharge behavior of sulfur-polypyrrole cathode material by LiNO3 electrolyte additive

    Self-discharge characteristics of Li/S cells using pure sulfur and sulfur-polypyrrole (S-PPy) cathode materials and lithium bis(trifluoromethane)sulfonimide (LiTFSI) as the electrolyte salt were investigated b...

    Enhanced rate performance of polypyrrole-coated sulfur/MWCNT cathode material: a kinetic study by electrochemical impedance spectroscopy

    Lithium-sulfur batteries have a poor cyclability and inferior rate capability due to the shuttle effect of lithium polysulfides. To solve these problems, a sulfur-coated MWCNT composite (S/MWCNT) was coated wi...
