So, how does the CO2 emissions of concrete production compare to that of Lithium ion battery production?

Wouldn't it be mitigated by only being created once and then have a very long lifetime of utilization (vs the battery form of storage)?




Depends on how much the inferiority of the concrete vs. that used for construction affects its durability and longevity. It needs to be able to withstand weight from blocks above, impact whenever it or an adjacent block is moved, and corrosion from any metallic material within.

I could almost imagine these blocks needing to be tougher over time than something made from cement used in construction, to avoid crumbling under those conditions.
