Journal ArticleDOI
Designing high-energy lithium–sulfur batteries
TL;DR: This review aims to summarize major developments in the field of lithium-sulfur batteries, starting from an overview of their electrochemistry, technical challenges and potential solutions, along with some theoretical calculation results to advance the understanding of the material interactions involved.
Journal ArticleDOI
Catalytic oxidation of Li2S on the surface of metal sulfides for Li−S batteries
Guangmin Zhou,Hongzhen Tian,Yang Jin,Xinyong Tao,Bofei Liu,Rufan Zhang,Zhi Wei Seh,Denys Zhuo,Yayuan Liu,Jie Sun,Jie Zhao,Chenxi Zu,David Wu,Qianfan Zhang,Yi Cui +14 more
TL;DR: It is demonstrated that the Li2S decomposition energy barrier is associated with the binding between isolated Li ions and the sulfur in sulfides; this is the main reason that sulfide materials can induce lower overpotential compared with commonly used carbon materials.
Journal ArticleDOI
Understanding the Anchoring Effect of Two-Dimensional Layered Materials for Lithium–Sulfur Batteries
Qianfan Zhang,Qianfan Zhang,Yapeng Wang,Zhi Wei Seh,Zhongheng Fu,Ruifeng Zhang,Yi Cui,Yi Cui +7 more
TL;DR: Insight is gained into how van der Waals interaction and chemical binding contribute to the adsorption of Li2Sn species for anchoring materials with strong, medium, and weak interactions, and it is discovered that too strong binding strength can cause decomposition of Li1Sn species.
Journal ArticleDOI
Amphiphilic surface modification of hollow carbon nanofibers for improved cycle life of lithium sulfur batteries
TL;DR: It is demonstrated that this capacity fading mechanism of the sulfur cathodes can be overcome by introducing amphiphilic polymers to modify the carbon surface, rendering strong interactions between the nonpolar carbon and the polar Li(x)S clusters.
Journal ArticleDOI
Understanding the Role of Different Conductive Polymers in Improving the Nanostructured Sulfur Cathode Performance
TL;DR: The capability of three of the most well-known conductive polymers in improving long-term cycling stability and high-rate performance of the sulfur cathode decreased in the order of PEDOT > PPY > PANI.
