Lithium/Sulphur batteries

[derrick7]

I recently saw a clip from a B.B.C. website about an aircraft, non-manned, that stayed up for 82 hours, the power was principally solar panels on the wings with Lithium/Sulphur batteries powering it at night. The clip said the new Lithium/Sulphur batteries had about 3 times the capacity of the best of the present Lithium batteries, does anyone know anything more of these batteries?
