Summary: Many kinds of nanostructured metal oxides were introduced in cathodes of Li–S batteries for high sulfur utilization and effective confinement for polysulfides. Herein, Gd2O3 nanoparticles modified wave‐like carbon host, which are derived from soybean residue by activation and pyrolysis processes. After the activated soybean residue derived carbon (ASC) host modified by Gd2O3 nanoparticles, the ASC‐Gd was integrated with sulfur by melting method and then used as cathode in lithium–sulfur (Li–S) batteries. According to the electrochemical results of ASC‐Gd/S cathode, a high initial discharge capacity (1343 mAh g−1 at 0.1 C) and improved cycling stability were exhibited, which was attributed to the strong adsorption ability for polysulfides and ultrahigh specific surface area of the ASC. As a result, the Gd2O3 nanoparticles modified wave‐like biomass carbon was a promising host material of Li–S batteries with high performances. [ABSTRACT FROM AUTHOR] |
