“…8,22 Moreover, lithium dendrites, changes in the volume and shape of the lithium anode, metallic Li anode cracking, and instability in the solid electrolyte interphase (SEI) are some of the disadvantages of using lithium as an anode electrode. 23 Over the past decade, researchers have poured time and energy into studying Li–S batteries and have offered several solutions to the problems listed above. 24–26…”

“…1T-MoS 2 cathode hosts have also proved very efficient for Li-S batteries [51,52] as they trap polysulfides and reduce their shuttling effect, while also acting as electrocatalysts [52,53]. Single atom catalysts on carbon hosts also have similar effects as electrocatalysts and in reducing the polysulfide shuttling effect [54][55][56][57][58].…”

In the pursuit of high energy density batteries beyond lithium, room-temperature (RT) sodium–sulfur (Na-S) batteries are studied, combining sulfur, as a high energy density active cathode material and a sodium anode considered to offer high energy density and very good standard potential. Different liquid electrolyte systems, including three different salts and two different solvents, are investigated in RT Na-S battery cells, on the basis of the solubility of sulfur and sulfides, specific capacity, and cyclability of the cells at different C-rates. Two alternative cathode host materials are explored: A bimodal pore size distribution activated carbon host AC MSC30 and a highly conductive carbon host of hollow particles with porous particle walls. An Na-S cell with a cathode coating with 44 wt% sulfur in the AC MSC30 host and the electrolyte 1M NaFSI in DOL/DME exhibited a specific capacity of 435 mAh/gS but poor cyclability. An Na-S cell with a cathode coating with 44 wt% sulfur in the host of hollow porous particles and the electrolyte 1M NaTFSI in TEGDME exhibited a specific capacity of 688 mAh/gS.
