A complete reaction mechanism is proposed to explain the sulfur conversion mechanism in room-temperature sodium-sulfur battery with carbonate-based electrolyte. The irreversible reactions about crystal sulfur and reversible two-step solid-state conversion of amorphous sulfur in confined space are revealed.
The as-developed sodium–sulfur batteries deliver high capacity and long cycling stability. To date, batteries based on alkali metal-ion intercalating cathode and anode materials, such as lithium-ion batteries, have been widely used in modern society from portable electronics to electric vehicles 1.
To examine the sulfur conversion mechanism of RT Na/S batteries, a series of composites containing varying amounts of sulfur have been synthesized using micro-mesoporous carbon host. A distinction can be made between the sulfur present externally and within the confined pores based on the analysis of their electrochemical behaviors.
Room-temperature sodium–sulfur batteries (NaSBs) are promising candidates for next-generation large-scale energy storage solutions.
Ambient-temperature sodium-sulfur (Na-S) batteries are potential attractive alternatives to lithium-ion batteries owing to their high theoretical specific energy of 1,274 Wh kg −1 based on the mass of Na 2 S and abundant sulfur resources. However, their practical viability is impeded by sodium polysulfide shuttling.
Sodium-sulfur batteries show potential as attractive alternatives to Li-ion batteries due to their high energy density but practicality is hampered by sodium polysulfide issues. Here, the authors introduce an intercalation-type catalyst MoTe2 to improve the redox kinetics in Na-S batteries.
