Cobalt in Nitrogen-Doped Graphene as Single-Atom Catalyst for High-Sulfur Content Lithium–Sulfur Batteries
Zhenzhen Du,Xingjia Chen,Wei Hu,Cheng-Hao Chuang,Shuai Xie,Ajuan Hu,Wensheng Yan,Xianghua Kong,Xiaojun Wu,Hengxing Ji,Li-Jun Wan +10 more
TL;DR: It is revealed that monodisperse cobalt atoms embedded in nitrogen-doped graphene (Co-N/G) can trigger the surface-mediated reaction of Li polysulfides to facilitate both the formation and the decomposition of Li2S in discharge and charge processes, respectively.

Zhenzhen Du,Chengkun Guo,Linjun Wang,Ajuan Hu,Song Jin,Taiming Zhang,Hongchang Jin,Zhikai Qi,Sen Xin,Xianghua Kong,Yu-Guo Guo,Hengxing Ji,Li-Jun Wan,Li-Jun Wan +13 more
TL;DR: The CVD-graphene on PP separator is the thinnest and lightest interlayer to date and is able to suppress the shuttling of polysulfides and enhance the utilization of sulfur, leading to concurrently improved specific capacity, rate capability, and cycle stability and suppressed self-discharge when assembled with cathodes consisting of different sulfur/carbon composites and electrolytes either with or without LiNO3 additive.

NS codoped carbon nanorods as anode materials for high-performance lithium and sodium ion batteries
TL;DR: In this paper, NS codoped carbon nanorods (NS-CNRs) were prepared using crab shell as template and polyphenylene sulfide (PPS) as both the C and S precursor, followed by carbonization in NH3.

TL;DR: In this article , a 1,1,3,3-tetramethylurea (TMU) solver was proposed for lithium-oxygen batteries, where a kinetically favorable one-electron Li2O2 oxidation pathway can happen in the urea electrolyte system, thus leading to a much lower charge overpotential compared to the tetraglyme-based LOBs.
