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:

Either it works or it doesn't! smile

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.
