Outline of Li–S Battery Project
2021In this project, Li–S batteries have been investigated by a team comprising 12 principal investigators. In particular, we focused on developing Li–S batteries with sparingly solvating electrolytes for cathode active materials. Prior to the start of our project, the dissolution of the discharge products of sulfur (lithium polysulfides: Li2Sx, x = 8 ~ 2)

Metalization of Li₂S particle surfaces in Li-S batteries.
Nanoscale, 2015The Li-S battery is the most promising candidate for future electric vehicles. The study of stabilities and conductivities of Li2S nanoparticles, which are used as pre-lithiated cathode materials, is crucial for the development of Li-S batteries. Here, we investigate the atomic and electronic structures as well as stabilities of Li2S surfaces and ...

Li–S batteries: simple approaches for superior performance
Energy & Environmental Science, 2013Although promising improvements have been made in the field of Li–S rechargeable batteries, they are still far from reaching the market place due to several drawbacks. To combat the solubility of polysulphides, confinement approaches aiming to trap sulphur within the cathode side have been pursued, but success has been limited.

Oxis Energy, a UK battery materials start-up, says it is fitting out a factory in Port Talbot, Wales, so it can begin the world’s first mass production of electrolyte and cathode materials for lithium-sulfur batteries. Products made at the Port Talbot plant will supply a Li-S battery-cell facility in the Brazilian state of Minas Gerais that Oxis is ...

Li‐S Battery Analyzed by UV/Vis in Operando Mode
ChemSusChem, 2013Battery watch: UV/Vis spectrophotometry is demonstrated as a powerful analytical method for the in situ study of polysulfides. Through the interactions that occur between different chain-length polysulfide molecules and the UV/Vis radiation, quantitative and qualitative determination of the polysulfides formed during Li-S battery operation can be ...

Semi-Solid Li-S Battery Electrolytes
ECS Meeting Abstracts, 2019The urge for electrochemical energy storage devices with high gravimetric and volumetric energy density is imminent and the lithium−sulfur (Li-S) battery has been poised as a major next generation battery concept candidate. While it has a (very) high theoretical energy density, low cost and non-toxicity of starting materials,[1] its practical ...
