Advantages: Sulfur is cheap and very light, good for packing more capacity into a lighter package???????????

Obstacles: Current versions have short lifetimes and the electrolyte needs work — it tends to dissolve the cathode and react with the anode

During discharge,

, lithium ions break away from the anode and swim through the liquid electrolyte to reach the sulfur cathode. There,

, the ions form a covalent bond with the sulfur atoms. Each sulfur atom bonds to two lithium ions, rather than just one, doubling the number of bonds in the cathode of the battery. More chemical bonds means more stored energy, so a lithium-sulfur battery creates more juice than a lithium-ion one. That, combined with sulfur’s light weight, means that,

, in principle,

, manufacturers can pack more punch for a given amount of weight, storing four or five times as much energy per gram.

, that upgrade could boost an electric vehicle’s range up to as much as 500 miles on a single charge. But first, researchers have to get past the short lifetime of existing lithium-sulfur batteries,

, which, Crabtree says, is due to a loss of lithium and sulfur in each charge-discharge cycle.
When lithium combines with sulfur, it also forms compounds called polysulfides,

, which quickly gum up the battery’s insides. Polysulfides form within the cathode during battery discharge,

, when stored energy is released. Once they dissolve in the battery’s liquid
