Energies, Vol. 11, Pages 1535: Preparation of Hierarchical Porous Carbon from Waterweed and Its Application in Lithium/Sulfur Batteries Energies doi: 10.3390/en11061535 Authors: Chunyong Liang Xiaomin Zhang Yan Zhao Taizhe Tan Yongguang Zhang Zhihong Chen A nanostructured carbon (NSC) material with a hierarchical porous structure is synthesized through the carbonization of a waterweed, namely Echinodorus amazonicus Rataj. The fabricated NSC is used as an electrode material for sulfur of lithium/sulfur (Li/S) batteries. The NSC provides for a high pore volume (0.19 cm3 g−1) and large specific surface area (111.25 m2 g−1). Because of the highly hierarchical porous structure of the NSC material, allowing polysulfides to remain in the carbon framework after cycling, the sulfur/NSC composite exhibits an excellent electrochemical performance.
