New battery idea gets lots of power out of unusual sulfur chemistry
Rather than being used as a storage material, the sulfur gives up electrons.

… a team of Chinese researchers has managed to turn sulfur’s complex chemistry into a strength, making it the primary electron donor in a sodium-sulfur battery….
the energy density can reach over 2,000 Watt-hours per kilogram.

@CTHW@mstdn.ca @arstechnica@mastodon.social that's around 10 times the energy density of lithium ion batteries! Amazing if that can be made to work even at half that energy density.

At that density a 123 KV F150 Lightning battery pack would weigh about 150 kg adding extra material needed to make the pack …
And that's one hell of a lot less than the 900 kg pack now ..
