Lithium-sulfur batteries have four times the energy density of lithium-ion batteries, according to ORNL, which means they should be able to hold a charge for much longer. Also, the material used ...

The researchers reported on a way to stabilize a rare form of sulfur in a cathode, which would allow it to function in the carbonate electrolyte used in commercial Li-ion batteries. Until now, sulfur ...

Lithium-sulfur is a holy grail of battery development, with capacity many times more than lithium ion alone. High-capacity electrodes swell in volume up to 78 percent and bust out of traditional ...

One such technology could be lithium-sulfur batteries: they store considerably more energy than their lithium-ion cousins – in theory as much as six times the energy for a given weight. What’s ...
