Iron-air rust batteries are also pretty intersting. Just iron, air and water to store power by exploiting how rust forms.
anything that's outside of rare metals batt technology either lithium or sodium based right now is basically off of the table, except for silver zinc iirc, and nickel hydrogen. Those are like the two options that are probably viable, everything else simply doesn't exist yet.
I'd just like to note that a lot of storage technologies that are currently in the pilot project stage are based on using components with existing supply lines to minimize the time and effort needed to scale up production.
to be specific, most of the shit like aluminum air batteries are still in the heavy research stages of production, we haven't even gotten them remotely close to lithium tech, such that lithium tech is still king.
Give it a decade and there will likely be more than a few types of batts kicking around though.
It's not about production scaling, that's the easy part, you just make and sell more product, we've been doing that since the 1800s. The hard part is making it market viable. Or even exist at all in the first place.
