Room temperature sodium-sulfur (RT Na-S) batteries attract many attentions since they endow many overwhelming merits, for instances, resources abundances of S and Na, high theoretical capacity of S (1672 mAh g-1), non-toxicity, and cost-efficiency. Nevertheless, the Na-S batteries are often restrained for their poor cycling performance and inferior Coulombic efficiency, which result from the sodium polysulfide (NaPSs) dissolution and the sluggish kinetics reactions. These issues always result in fast active materials loss and rapid cycling decay. To overcome these challenges, preventing the re...

CVD was used to produce a nanometric hexagonal boron nitride coating on the cambered sides of every fiber in graphene glass fiber fabric.

Room temperature sodium-ion batteries are the most likely alternative to lithium-ion batteries, and are considered one of the most promising candidates for large-scale energy storage. On the anode side, metallic sodium, with an ultra-high theoretical capacity and a low redox potential, has been considered the most promising material for batteries with a high energy density. However, the use of a sodium metal anode has met some challenging problems, such as the growth of sodium dendrites, side reactions between sodium metal and the electrolyte, and large volume changes during charge and dischar...
