What I like that I'm hearing about this CO2 battery, whether true will have to be seen, is that it might rely on off the shelf components, that's great, means the supply chain can be simple, and has longer life in the first place. And that while potentially even cheaper?
If your process gets 90% of the lithium out of the battery, after 7 cycles more than half of the lithium is gone. Therefore Mining can’t stop even when the market doesn’t grow anymore.
We don't know how long that process will go on, but in any case the amount of lithium needed will be a steady state, assuming constant need for batteries. But much more likely we will see ever increasing demand for batteries, just as we do for steel or copper or whatever minerals power our current economy.
