Lithium CO2 batteries

Potential battery breakthrough? 

Lithium CO2 could be 7 times more energy dense than ordinary lithium batteries, providing possibly 1800 watts per kg of storage.

No idea how credible this is but it is from a respected university...and seems to have aroused a lot of interest. ]

It would make night storage of solar power economic, assuming a similar cost profile per kg compared to current lithium batteries.

Re: Lithium CO2 batteries

Have heard of zinc air batteries in the past so other metals would be possible. Not sure of who well it might work.
Thats were actual papers and research must be had to gain knowledge.

Re: Lithium CO2 batteries

I deliberately didn't link to the paper because I wasn't sure it added a lot...but here you go:

https://onlinelibrary.wiley.com/doi/abs … .201902518

Either it works or it doesn't!

Re: Lithium CO2 batteries

The chemical reactions are what you look to for how the battery will respond to chaging and discharging under normal operations. Its using co3 with the O changing places in the chemistry to produce the charge change while in use.

Re: Lithium CO2 batteries

The article at the link below reports on what (sounds like) a significant advance in electric battery electrode design ...

https://www.yahoo.com/news/electric-car … 17690.html

While lithium-ion batteries use graphite as an electrode, the StoreDot battery works faster by replacing graphite with semiconductor nanoparticles that allow ions to pass more easily and quickly. The company expects to replace this electrode with silicon, a much cheaper component, by the end of the year.

Tesla is also working on developing silicon electrodes.

Re: Lithium CO2 batteries

Louis introduced this topic and SpaceNut picked up on it ....

If someone has time to investigate to see if anything happened after the initial press release flurry, I'd definitely be interested.

I've added a topic to focus specifically on Lithium-Sulfur batteries....

SpaceNut created a topic for ** any ** battery that uses lithium...

Re: Lithium CO2 batteries

The main issue is unless we find more lithium deposits we do not after much analysis by kbd512 that we do not have enough to make the storage batteries that we need no matter what the second material is.
