Recent Advances of Freestanding Cathodes for Li‐S Batteries

Chemistry – An Asian Journal, 2021
AbstractLithium‐sulfur batteries (LSBs) with high energy density and low cost have been recognized as one of the most promising next‐generation energy storage systems. Although it has taken decades of development, the practical application of LSBs has been hindered by several inherent obstacles, particularly the severe shuttle effect and sluggish ...

New electrolyte improves Li-S batteries

C&EN Global Enterprise, 2018
Lithium-sulfur batteries can pack up to five times as much energy by weight as some lithium-ion batteries, in principle. In practice, experimental versions of the batteries have fallen short of expectations because of unwanted chemical reactions between the electrodes and the electrolyte solution that alter the electrodes, thereby reducing energy ...

Li–S batteries: simple approaches for superior performance

Energy & Environmental Science, 2013
Although 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.

Equivalent Circuit Modelling of Li-S Batteries

ECS Transactions, 2021
The presented article describes a Multi-Scale Multi-Domain model of a Li-S battery using an equivalent circuit model consisting of R-C pairs. The parameters of the equivalent circuit model were obtained by fitting experimentally measured results from electrochemical impedance spectroscopy at various states of charge.

Insight into Sulfur Reactions in Li–S Batteries

ACS Applied Materials & Interfaces, 2014
Understanding and controlling the sulfur reduction species (Li2Sx, 1 ≤ x ≤ 8) under realistic battery conditions are essential for the development of advanced practical Li-S cells that can reach their full theoretical capacity. However, it has been a great challenge to probe the sulfur reduction intermediates and products because of the lack of methods.

Metalization of Li₂S particle surfaces in Li-S batteries.

Nanoscale, 2015
The 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 ...
