It is urgent to develop fast-charging batteries to eliminate the charging concerns when using electric vehicles. The fluid nature of liquid sulfur was found to enhance areal capacities and contribute to lithium-sulfur (Li-S) fast-charging batteries. However, the deposition kinetics of liquid sulfur in Li-S batteries remain underexplored.
A typical discharge profile of the lithium–sulfur battery has two discharge plateaus at 2.3 and 2.1 V, which represent the conversions of S 8 to Li 2 S 4 and Li 2 S 4 to Li 2 S, respectively. In addition, at the end of discharge, Li 2 S is formed as the voltage drops.
The fluid nature of liquid sulfur was found to enhance areal capacities and contribute to lithium-sulfur (Li-S) fast-charging batteries. However, the deposition kinetics of liquid sulfur in Li-S batteries remain underexplored. This study uses a micro-battery device to track the in-situ deposition of liquid sulfur on carbon film.
Rechargeable lithium–sulfur (Li–S) batteries, featuring high energy density, low cost, and environmental friendliness, have been dubbed as one of the most promising candidates to replace current commercial rechargeable Li-ion batteries.
(American Chemical Society) The Li/S battery is a promising electrochem. system that has a high theor. capacity of 1675 mAh/g-1, but its discharge mechanism is known to be a complex multistep process. As the active material dissolves during cycling, this discharge mechanism was studied through the electrolyte characterization.
Among these front-runners, rechargeable lithium–sulfur (Li–S) batteries have established a reputation in academia and the industrial community owing to their ultrahigh theoretical energy density (2600 Wh kg −1), low-cost raw materials, and environmental friendliness. [17 - 19] Therefore, its practical applications are highly anticipated.
