Lithium-sulphur batteries


Batteries made with sulfur could be cheaper, greener and hold more energy:

https://www.abc.net.au/news/2020-01-08/lithium-sulfur-battery-greener-cheaper-and-more-efficient/11849590

lithium-sulfur batteries: they store considerably more energy than their lithium-ion cousins -- in theory as much as six times the energy for a given weight. What's more, they can be made from cheap materials that are readily available around the world.

What interested me about the article, dorian

Was the snip I have placed below
The other key ingredient in these batteries is of course lithium.
Given that Australia is a leading global producer, we think it is a natural fit to make the batteries here.

I did read (many years ago), that the main reason for not having a battery breakthrough, was that there was no market for them
Someone, (many years ago), predicted that when there was a market to sell batteries, commercial enterprise, would start investing in battery research

I can only hope that this battery, and others in the research stage, prove marketable

Well thanks a lot Dorian! you have ruined my day, LOL

That's just what I needed to hear, Sulpha batteries. To start with I thought you meant phosphate iron batteries, I read the article, Oh! boy. I have spent the last couple of days researching

LifePo4 batteries for my van. Had one all picked out. I did hear rumors about "solid state" batteries. Thought they would be a long way off. I'm not a greenie but I love sustainable energy have

self sufficient solar, so no power costs at home. SO NOW, I will have to rethink and hold off with my old nearly dead battery.

I hope they get it perfected it would be a win- win for our country. Sounds fantastic. PS thanks Dorian I really do appreciate this info.

 Greener?  There is a lot of conflicting evidence out there at the moment about things like lithium and electric vehicles. This is a lithium mine- green?

If the claims of increased energy density are realised, then it seems to me that the payback period in EV applications may be substantially reduced, which means that the net green advantage would be reached much earlier in the vehicle's life cycle. That alone could revolutionise the patterns of energy consumption. In fact it may even radically change the economics of domestic energy storage.

But then we've heard this all before with other technologies, so I'm not holding my breath.
