In theory, a Li-S chemistry should be able to outperform Lithium Ion NCM chemistries by a factor of two or three.
Operating temperature range and cycle endurance were some primary barriers, and this seems promising, but ...
"The researchers suggest more work is required to improve the energy density and perhaps to find other materials to use for the mix to ensure a low-weight battery."
ok, nevermind.
If it's written like this it must be quite low..
Note though that 'grid batteries' are a very important part for solar transition and they have very different requirement for weight and energy density than electric cars..
