In light of the scarce lithium resources and unevenly distribution around the world, it is keen to develop RT Na–S batteries with the sulfur cathode and sodium anode, holding the advantages of abundant resources and low cost. [ 12 ]
Room-temperature sodium–sulfur (RT Na–S) batteries have become the most potential large-scale energy storage systems due to the high theoretical energy density and low cost. However, the severe shuttle effect and the sluggish redox kinetics arising from the sulfur cathode cause enormous challenges for the development of RT Na–S batteries.
Introduction Sodium-sulfur (Na-S) batteries with sodium metal anode and elemental sulfur cathode separated by a solid-state electrolyte (e.g., beta-alumina electrolyte) membrane have been utilized practically in stationary energy storage systems because of the natural abundance and low-cost of sodium and sulfur, and long-cycling stability , .
To make deep understanding on the mechanism of unique sulfur cathode, CV, in situ Raman spectroscopy as well as in situ synchrotron XRD (Figure 5d) were conducted and revealed the two-step reaction mechanism with the reduction of solid sulfur to soluble long-chain NaPSs and then to short-chain Na 2 S y (1 < y ≤ 3).
In the latest study, Xia and coworkers [ 53 ] proposed the one-step mechanism of the RT Na–S batteries with the slit ultramicropore carbon (derived from the coffee residual) as host to confine small sulfur molecules (S 2–4) through a traditional melting-diffusion method (Figure 2b).
Thus, construction of sulfur hosts with confinement–adsorption–catalysis effects could effectively improve the electronic conductivity, the ion diffusion kinetics, and the rapid conversion of solvable NaPSs to the final reduction products of Na 2 S 2 /Na 2 S, resulting in satisfying performance for the RT Na–S batteries.
