The carbon-nanovessels enclosing the sulfur not only increase the service life of sodium-sulfur batteries, but also their storage capacity: as the sulfur is fixed in the cage, it is almost completely ...

a byproduct formed as a result of the reaction between sodium and sulfur. This byproduct keeps moving back and forth between the two electrodes, reducing battery performance and capacity (also ...

But this week, researchers described a lithium-sulfur battery that still has over 80 percent of its original capacity after 25,000 charge/discharge cycles. All it took was a solid electrolyte that was ...

cell reaction uniformity, and sulfur migration, offering insights to address these issues and improve battery performance.
