Yeah, I think massive chemical batteries for storing excess electricity to facilitate a contrived green energy market is a bad idea.

You’re right, but I think less dense but safer and more sustainable options are the better choice for this
We can all agree on that, Clearly li-ion is a bad choice for static use cases.
But right now it’s the cheapest option, and it looks likely that will stay true for quite a while unfortunately.
It’s the densest option. The cheapest is probably salt/water or iron/water using scrap
LIthium Iron Phosphate is cheapest relatively dense battery type. Sodium ion will be if lithium get expensive.
You can draw an arbitrary line of density you find good enough. But with how much space us wasted in some countries, that line should vary a bit place to place
With 40 foot containers providing utility or smaller scale storage solutions of 2.9mwh per container with LFP batteries, that is about 170mwh per acre. Before stacking. I don’t believe a lack of density matters anywhere in the world. Spare space inside buildings is usually sufficient for building needs.
A lack of density definitely matters in some places. I’ve been to a bunch of countries now, some have plenty of space, some really don’t
Weirdly it’s not, except maybe gravity batteries where nice reservoirs happen to exist already. It should be but it’s not right now.
Li-ion has economy of scale right now. I do think molten metal etc will overtake eventually, but they’re currently playing catchup and li-ion has dropped in price so much over time that it’s surprisingly cheap even where it should make no sense.
