New Insight into the Working Mechanism of Lithium–Sulfur Batteries under a Wide Temperature Range

Autor: Guiping Peng, Chunxi Hai, Xiang Li, Sun Yanxia, Guotai Zhang, Chao Sun, Yuan Zhou, Shengde Dong, Shen Yue, Zeng Jinbo

Publikováno v: ACS Applied Materials & Interfaces. 13:55007-55019

Sweet potato-derived carbon with a unique solid core/porous layer core/shell structure is used as a conductive substrate for gradually immobilizing sulfur to construct a cathode for Li-S batteries. The first discharge specific capacity of the Li-S ba

Highly Catalytic Boron Nitride Nanofiber In Situ Grown on Pretreated Ketjenblack as a Cathode for Enhanced Performance of Lithium–Sulfur Batteries

Autor: Junchao Zheng, Jing Mao, Chunxi Hai, Shengde Dong, Kehua Dai, Guotai Zhang, Chao Sun, Xiang Li, Ren Xiufeng, Yuan Zhou, Zeng Jinbo, Shen Yue, Sun Yanxia

Publikováno v: ACS Applied Energy Materials. 3:10841-10853

To effectively avoid the shuttle effect of polysulfides between the cathode and anode, a boron nitride (BN)-Ketjenblack-xKOH@S composite (x means 1, 2, and 3 M) cathode for lithium–sulfur batteries...
