Big Ford EV Announcement Coming Aug 11th

They can obviously be recycled, but its far more expensive than just mining new materials.

Or cheaper. A used battery is 1000x richer source of raw materials than ore from a mine.

And the materials in the battery are not consumed.

You didn't answer. And in doing so did answer that your brother doesn't know Jack.

I am a retired engineer for whom my daily driver has been an EV for 12 years. Often eat lunch with a manager who works for the local electric utility. "What is the big problem with EVs on the grid? Not knowing when 250 kW loads will suddenly appear." He said looking at the raw data for my account he can't really see the EV. Looks too much like a heat pump.

LOL. Interesting, especially since you don't know my brother or much about the NY grid. Best we stop here or one of us is going to get booted, since you're quick with dishing out insults this thread can take an ugly turn.

No. Those darned innovative capitalists will find ways to make money off used and depleted batteries.

Oh wait, they are doing that right now, if you'd bother to search.

One of the greatest utilizations of a used EV battery is to repurpose for home energy storage. An EV battery with 50% of it's original capacity simply has less energy density than it used to have, otherwise works just fine. Usually only one module goes sour so disassembly of the battery yields a number of high capacity modules to build home energy storage.

I think there's some genuine concern to be had for this process when it isn't with LiFe batteries, as most lithium-based batteries get more prone to shorting and producing fires as they age and dendrites form, and that's certainly not something you want happening in your home. A robust BMS would be an absolute must in this usage case, as well as a containment system that prevents fire spread in the case of an event. From a reuse perspective, it's absolutely the "right thing", as avoiding disposal is key to reducing the overall lifecycle emissions of the product.

I don't see any but Chinese batteries catching on fire.

Are you including grid-scale battery fires (of which there are many examples)? How about Samsung's phone battery fires? GM's recall of the Chevy Bolt (for fires)?

Yes, Chinese batteries (and in particular cheap Chinese goods using Chinese batteries like e-bikes/scooters...etc) are the most numerous in their examples, but the risk exists with all the major lithium-based chemistries (considerably less for LiFe as noted) and aged batteries present higher risk than new batteries (due to dendrite formation for example), so one needs to be even more careful, and take greater precautions when repurposing cells, particularly when they will be co-located with a huge number of other cells, and placed inside a domicile.
