What it says in the link sounds very promising! It sounds like the specific energy (which the amount of maximum energy stored per unit mass and not to be confused with energy density) of this new battery, if fully developed, would be much higher than that for the the highest specific energies for commercially available lithium batteries today but I find it hard to tease out from the link even a approximation of how much more specific energy we are talking about here.
“.... The sulfur cathode stored up to five times more energy per sulfur weight than today's commercial materials....” but that is just for the Cathode.
It also says:
“...Cui's group has demonstrated a succession of increasingly capable anodes that use silicon rather than carbon because it can store up to 10 times more charge per weight. ...” but that is just for the anode.
So, I guess, putting these two fragments of info together and assuming that both the sulfur cathode and the silicon anode will be combined into the same battery, we could be talking about overall very roughly ~7 times more specific energy?
