Combining theory and experiment in lithium–sulfur batteries: Current progress and future perspectives
TL;DR: In this paper, the typical applications of computational chemistry in Li-S battery studies, correlating to characterization techniques, such as X-ray diffraction, infra-red & Raman spectra, X -ray absorption spectroscopy, binding energy, and nuclear magnetic resonance, are reviewed.

Lili Shi,Seong-Min Bak,Zulipiya Shadike,Chengqi Wang,Chaojiang Niu,Paul Northrup,Hongkyung Lee,Arthur Y. Baranovskiy,Cassidy S. Anderson,Jian Qin,Shuo Feng,Xiaodi Ren,Dianying Liu,Xiao-Qing Yang,Fei Gao,Dongping Lu,Jie Xiao,Jun Liu,Jun Liu +18 more
TL;DR: In this paper, the authors investigate the reaction processes and their correlation to cell cycling behavior and failure mechanisms, and find that catastrophic failure of high-energy Li-sulfur (Li-S) pouch cells results from uneven sulfur/polysulfide reactions and electrolyte depletion for the first tens of cycles.

Electrocatalytic activity of lithium polysulfides adsorbed into porous TiO 2 coated MWCNTs hybrid structure for lithium-sulfur batteries
Xiulin He,Huijie Hou,Xiqing Yuan,Long Huang,Jingping Hu,Bingchuan Liu,Jingyi Xu,Jia Xie,Jiakuan Yang,Sha Liang,Xu Wu +10 more
TL;DR: A novel composite MWCNTs@TiO2-S nanostructure is reported by grafting TiO2 onto the surface of MWC NTs, followed by incorporating sulfur into the composite, which exhibited the highest electrochemistry performance among all compositing ratios of M WCNTs/TiO 2.

Surface chemistry of lithium in 1,3-dioxolane
TL;DR: In this paper, Li-formate is found to be one of the major species formed on Li in dioxolane, and Li is used as a cleaning agent for ether solvents, and the electrochemical behavior of methyl formate-Li salt/CO2 solutions have enabled a more accurate identification of surface films formed on lithium in 1,3-dioxolanes.

A self-discharge model of Lithium-Sulfur batteries based on direct shuttle current measurement
Vaclav Knap,Daniel Loan Stroe,Maciej Swierczynski,Rajlakshmi Purkayastha,Karsten Propp,Remus Teodorescu,Erik Schaltz +6 more
TL;DR: In this paper, a simple but comprehensive mathematical model of the Li-S battery cell self-discharge based on the shuttle current was developed and is presented The shuttle current values for the model parameterization were obtained from the direct shuttle current measurements.

The propagating species in the polymerisation of 1,3‐Dioxacycloalkanes by Perchloric Acid
TL;DR: In this article, the authors discriminate between the two principal rival theories concerning the polymerisation of 1,3-dioxacycloalkanes by anhydrous perchloric acid, the Mainz theory and the Keele theory, by means of Jaacks's method for determining tertiary oxonium ions.
