First-principle calculations were employed to further analyze the interaction between Na polysulfide/Na2S and cathode components as well as electrolyte solvents. 9, 2444624450 (2017). 12). They achieve high energy densities of 150-240 Wh kg 1 [61]. Proc. This is clear evidence that the solubility of Na polysulfides in FEC or in concentrated electrolyte is so low that only trace amounts of Na2S and Na2S2 are depositing on the Na anode. 2d and Supplementary Fig. All procedures for electrolyte preparation were carried out in an Ar-filled glove box (MBraun) with the concentrations of moisture and oxygen below 0.5ppm. Our sodium battery has the potential to dramatically reduce costs while providing four times as much storage capacity. Combining these two abundant elements as raw materials in an energy storage context leads to the sodium-sulfur battery (NaS).

X-ray photoelectron spectroscopy (XPS) measurements were performed to investigate the surface components of these Na anodes. One of the main shortcomings of traditional sodium-sulfur batteries is that they require high temperatures to operate. Cyclic voltammograms (CVs) of the assembled cells were tested using the VMP3 electrochemical working station at a scanning rate of 0.1mVs1. The fundamental kinetics of the electrocatalytic sulfur reduction reaction, a complex 16-electron conversion process in lithium-sulfur batteries, is a topic that remains largely unexplored. It used liquid sulfur for the positive electrode and a ceramic tube of beta-alumina solid electrolyte (BASE). Mater. Energ. This means that they must be preheated before use, and that they will consume some of their stored energy (up to 14%) to maintain this temperature when not in use. In order to solve problems associated with flammability, explosiveness and energy loss caused by high-temperature use conditions, most research is now focused on the development of room temperature sodium-sulfur batteries.

Electrochemical impedance spectra (EIS) of cells was examined using the VMP3 multichannel electrochemical station in the frequency range of 102 to 105Hz by applying a disturbance amplitude of 5mV. It should be noticed that in LiS batteries, the nucleophilic sulfide anions actively react with carbonate solvents via nucleophilic addition or substitution reaction, which results in a rapid capacity fading34. The strength of the SEI layer generally cannot bear the mechanical deformation during Na-ion plating/stripping processes, and hence leads to formation of surface defects and then growth of dendrites from these defects20. 2c. Considering a mid-value discharge voltage of ~1.4V, the corresponding energy density is around 1477Whkg1 and 886Whkg1 calculated based on the mass of sulfur and S@C composite, respectively.
