@rm_dash_r_star @notapantsday Is LMFP actually available in quantity? Wikipedia suggests not.
The problem with sodium ion batteries, apart from lower density, is that they have a shorter lifespan. On the upside they’re easier to recycle. IIRC there was some recent research that might fix the lifespan problem.
@rm_dash_r_star @notapantsday Unfortunately batteries with nickel are still pretty widely used. However it’s definitely going in the right direction.

In any case digging up fossil fuels is also pretty dirty, and has been known to pollute indigenous people’s drinking water, steal their land, and on occasion pay for private militias and government troops to put down protests.
Obviously electric buses are preferable to electric cars. Public transport is worth investing in.
Also on batteries, iron-air is promising for grid storage, but not likely to be used for vehicles.

There isn’t much in industry exempt from that kind of thing, but countries go to war over access to oil. Anything that reduces consumption is good for mankind.
@rm_dash_r_star My point was simply that the danger to the Global South, and people in general, from continued fossil fuel extraction is greater than that from the extraction needed for the transition.
We can reduce the material demands of the transition somewhat by demand reduction etc, but we’re not comparing a new lithium mine taking people’s land to nothing. We’re comparing it to oil wells polluting people’s drinking water *and* killing their crops with droughts and floods *and* rising sea levels destroying AOSIS etc.
By all means try to do it in a cleaner, fairer, more just way. But rare earths, or even cobalt, aren’t a reason to stop the transition, which seemed to be the agenda of the person I’ve now blocked here. We need appropriate, better technology. And we can’t eliminate all road vehicles overnight, though we can reduce them somewhat.
No doubt I’m preaching to the converted now though. 😀

I realized that, I put an edit on there to not specify LMFP which has only been used in EVs in a limited fashion. I was confusing NMC which is actually the most common, oops. I changed it to a generic reference.

I’ve read differing reports on that. But yeah, cycle life is a big deal. In general it’s not great for the common Li-Ion types. LFP has pretty amazing cycle life, about five times greater and rivals the NiMH king. In many cases it’s well worth the additional size and weight, but for things sensitive to it like cars and handheld devices it’s a problem.
@rm_dash_r_star Yeah hopefully LFP for short term grid storage, maybe iron-air for long-term, though there are a few other options. Unfortunately nearly every option for long-term storage is very immature.
