Nitrogen-Doped CoSe2 as a Bifunctional Catalyst for High Areal Capacity and Lean Electrolyte of Li–S Battery

, 2020
The sluggish redox kinetics of polysulfides and difficult oxidation process of Li2S severely hinder practical application of Li–S batteries under high sulfur loading and a low electrolyte dosage.

Li–S batteries: Firing for compactness

Nature Energy, 2017
Conventional Li–S batteries have a non-compact cathode structure containing low areal loading of active materials. Now, a strategy of burning Li foils in a CS2 vapour is presented, which leads to the formation of highly compact Li2S nanoparticles as a lithiated sulfur cathode, offering promising battery performance.

Engineering Cooperative Catalysis in Li–S Batteries

Advanced Energy Materials, 2023
AbstractLithium–sulfur (Li–S) batteries are regarded to be one of the most promising next‐generation batteries owing to the merits of high theoretical capacity and low cost. However, the aprotic S electrochemistry is hampered by the shuttling effect and sluggish conversion of soluble lithium polysulfides (LiPSs).

Outline of Li–S Battery Project

2021
In 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)

Li–S Battery Using Li2S Cathode

2021
A major drawback of Li–S cells is the dendritic growth of Li metal and the formation of dead Li that occurs in cells during the charging/discharging processes, which causes the loss of electrochemically active Li, the depletion of the electrolyte, and the internal short circuit of the cell, and therefore prevents the safe use and long cycling-life of ...

Semi-Solid Li-S Battery Electrolytes

ECS Meeting Abstracts, 2019
The 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 ...

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 ...
