Ford is cutting production of the electric F-150 Lightning pickup. Although sales increased by 55 percent last year, they're growing more slowly than the company anticipated.
An 800v LiFePo truck would actually be able to tow reasonably as chargers improve. You’d have to stop every 120mi and change for 10-15 mins but I could live with 15 min stops every two hours.
Plus they don’t have thermal runaway and burn your fucking house down while charging.
One of the biggest challenges with mass EV battery production is making sure performance stays somewhat flat across the entire market you’re selling them in. Typically, LiFePo batteries perform better at higher temperatures than other chemistries, at the expense of low-temperature performance.
This works well, as long as
These batteries are only in vehicles sold in warmer climates
Customers never drive these vehicles into cold climates.
#1 is much easier to enforce as a manufacturer, but customers will be pissed if they move north, and their vehicle has worse range and power.
Li-ion has a flatter temp/performance curve, so it’s more suited to geographically larger markets like the US, where regulations require a single range number for the entire country, despite the significant climate variance
Energy density. NMC batteries are 50+% better when it comes to energy density so you can pack more energy storing capacity for the same weight
Edit : I read up and my percentage figure is off. I was deriving numbers from some old articles. Currently it seems NMC batteries have around 20℅(? Please correct me if I am wrong again) better energy density.

I don’t understand why EV use Li-ion or Li-po in the first place. LiFePo is clearly a superior choice for something like an EV.
