Reply to comment by Steakosaurus in Ford’s EVs are getting faster charging and more affordable batteries thanks to new chemistry by Ssider69

Lifepo4 have amazing life though. Iv got a 15 year old pack still at 50%+ capacity.

I mean, 50% sucks, but most other packs would be refusing to charge by now, or sagging too much to run the load. Means 5 year old 2nd hand trucks might be usable without a new battery if the owner doesn't need more then 75% range.

The essentially infinite recycling potential of nickel packs is better for the planet, though. And since they can be recycled easily, you should be able to get more money for a dead pack.

Currently battery is warrantied to 70% for 8yr or 100k mikes.

That may be a selling point for a small niche of drivers, but telling someone that their vehicle will degrade to roughly half the already low range is going to be a hard sell.

LFP struggles to hit something like 300 miles in very large packs, degrading to ~150 miles in a few years and having further reduced performance when it's cold out is a really hard sell.

15 years is not a few years

The battery did not degrade to 50% capacity in 15 years, unless it was barely used and babied for the entirety of that time.

Capacity degradation happens over the life of the cell and you can see substantial loss in 3-5 years of normal use.

So when you're starting with a chemistry that's already poor on range, and then reducing that range by 20-30% within the first 5 years of it's life, you can see where customers would be unhappy with the performance.
