Customer ServiceCarbon materials are the key hosts for the sulfur cathode to improve the conductivity and confine the lithium polysulfides (LiPSs) in lithium–sulfur batteries (LSBs), owing to their high electronic conductivity and strong confinement effect.
Moreover, sulfur and lithium sulfide, which constitute the active material in the cathode, are intrinsically insulating, complicating efforts to increase the active material content in the cathode and fabricate thick cathodes with high conductivity. These issues have long stood in the way of Li–S batteries achieving commercial viability.
The high capacity and energy densities of lithium sulphur batteries make them promising for applications, but their widespread realization has been hindered by problems at the interface between the cell components.
Therefore, a variety of freestanding activated carbon such as carbon fiber, carbon cloth, and carbon aerogels were developed to serve as the sulfur hosts of Li-S batteries instead of the traditional carbon powders [, , , , , , ].
The gap between the current achievements and the practical LSBs in real-market is bridged. Taking advantage of a high theoretical energy density of 2567 Wh kg -1, lithium sulfur batteries (LSBs) have been considered promising candidates for next-generation energy storage systems.
One of the most promising candidates for storage devices is the lithium–sulphur cell. Under intense scrutiny for well over two decades, the cell in its simplest configuration consists of sulphur as the positive electrode and lithium as the negative electrode 3, 4.
