Chemistry Scientists developed a new lithium-sulphur battery with a capacity five times higher than that of lithium-ion batteries, which maintains an efficiency of 99% for more than 200 cycles, and may keep a smartphone charged for five days. It could lead to cheaper electric cars and grid energy storage.

TLDR: Promising future research, unfortunately, lithium sulfur batteries degrades too quickly (due to volume change from charged to discharged of about 78%).

In my opinion, if you are looking for new battery tech that might hit the market sooner than this one, lookup "solid state batteries", very intesting :)

That should be manageable with thermal control, keep the battery in the right thermal regime for its charge level so the electrolyte has the correct fluidity for that state.

Sigh, going to research a patent, had some ideas.
