The practical application of room-temperature sodium-sulfur (RT Na-S) batteries was severely hindered by inhomogeneous sodium deposition and notorious sodium polysulfides (NaPSs) shuttling. Herein, novel sodium thiotellurate (Na2TeS3) interfaces are constructed both on the cathode and anode for Na-S batteries to …
The standard electrode (reduction) potentials of these two half-reactions indicate water may be oxidized at a less negative/more positive potential (–1.229 V) than chloride ion (–1.358 V).Thermodynamics thus predicts that water would be more readily oxidized, though in practice it is observed that both water and chloride ion are oxidized under typical …
Sodium is one of the most abundant elements in the earth crust; hence, it attracts an increasing interest as material for energy storage alternative to lithium [] spite higher weight and less negative redox potential with respect to lithium, i.e., 23 g mol −1 compared to 7 g mol −1 and − 2.7 V compared to − 3.0 V vs. SHE, respectively, sodium …
The increasing energy demands of society today have led to the pursuit of alternative energy storage systems that can fulfil rigorous requirements like cost-effectiveness and high storage capacities. Based fundamentally on earth-abundant sodium and sulfur, room ...

1. Introduction. In response to the demand for increased energy density and reduced raw material costs, room temperature sodium-sulfur (RT Na/S) batteries have garnered growing attentions [1], [2], [3].To enhance the conductivity and utilization of sulfur, a range of efficient hosts have been constructed, encompassing carbon-based and …
Herein, we investigate a lowly flammable electrolyte formed by dissolving sodium trifluoromethanesulfonate (NaCF3SO3) salt in triethylene glycol dimethyl ether (TREGDME) solvent as suitable medium for application in Na-ion and Na/S cells. The study, performed by using various electrochemical techniques, including impedance …
Chemical hazards of elemental sodium and sulfur are rather substantial due to the high negative enthalpy of the reaction at 350 °C (Δ H = −420 kJ mol −1). 105 Bulk sodium is stored in a corrosion resistant safety tube 103 equipped with a small supply hole at its base that regulates the flow of sodium and also allows a minimum amount of ...
