@ventoriffic Hey Ventoriffic. I just want to re-direct you a bit, its going to be a semi long post.
The current battery used in a OW is a Lithium Iron Phospate oxide (Li-Fe-PO4, or LFP), these are basically the safest batteries around. A Li-Po is a Lithium Polymer Battery which uses a semi-solid gel like substance for electrolytic magic.
The NMC as mentioned, is a so called Lithium Nickel Manganese Cobalt battery, which achieves a higher energy density than LFP, but has certain drawbacks aswell. (expect shorter battery lifecycles with NMC)
A quick comparison of LFP vs NMC
Pros with a LFP :
Very Stable (even at full charge)
Flat Voltage throughout use ( Very low voltage drop as you deplete the battery)
High Charge/Discharge rates (lots of amps!!)
Little risk of thermal runaway (No Kaboom)
Supreme Longevity ( going to last you forever!)
Higher discharge rate when not in use (compared to other batteries)
Lower Energy Density
Lower voltage (3.2-3.6 V)
Pros with NMC:
Higher Energy Density ( More milage, less bulk) Basically the selling point for the XR
Higher Voltage ( More Power!(ish) 4-4.2 ish)
A subsequent consequence of higher voltage is the ability to drive faster, as electric motor RPM limiter is
Voltage. Of course if you cant give it the torque (amps) it doesnt matter.
Worse longevity (expect about half of LFP life)
Higher risk for Thermal Runway ( not as bad as phone batteries tho)
Longer Charge times ( Cannot be charged as fast)
Higher production cost ( which is why you pay more)
There seems to be a lot of sacrifices with this model, for the big advantage of the increased range. Its going to be interesting to see how FM deals with this new chemistry, but expect a different beast. One that, maybe doesnt grow as old as the O+.
I also suspect the accelerations are going to differ, and charging times are going to go up. (if the battery capacity is double the O+, i expect the charging time to be 4 times as much, due to battery limitations)
I also do want to point out that most EV's are leaning toward NMC as an intersection point in safety, longevity, and power.
