Long-lasting Lithium-Sulfur Battery Promises to Double EV Range:
"By designing a novel robust cathode structure, researchers have now made a
lithium-sulfur battery that can be recharged several hundred times. The cells have an
energy capacity four times that of lithium-ion, which typically holds 150 to 200 watt-
hours per kilogram (Wh/kg). If translatable to commercial devices, it could mean a
battery that powers a phone for five days without needing to recharge, or quadruples
the range of electric cars.
That’s unlikely to happen, since energy capacity drops when cells are strung together
into battery packs. But the team still expects a “twofold increase at battery pack level
when [the new battery is] introduced to the market,” says Mahdokht Shaibani, a
mechanical and aerospace engineer at Australia’s Monash University who led the work
published recently in the journal Science Advances."
