That might be, I'll need to run the numbers to see. We'll need to wait and see just how many miles a battery is typically used before a car is junked. It could be so, but it is yet to be seen, even though there are some high-mileage EVs around, we don't know yet what the typical case will be.
That might be????? It is EXACTLY what it is!!! The 150,000 km is already nonsense as many Bolts easily reached this number without large amounts of battery failure. Maybe if we were talking passively cooled Nissan Leafs I would agree with that 150,000 km number. I still don't agree with that
1 paper that says a battery takes between 150 kg to 300 kg (1 to 2 g / kWh / km for 150,000 km of battery lifespan) to make 1 kWh of battery. The average numbers are 70 kg to 110 kg (0.47 to 0.73 g / kWh / km for 150,000 km of battery lifespan) according to many sources. But you can't make your point using average data, you need to use that
1 paper for your argument. Below is data to show that the 150,000 km value is nonsense.

I am going to do your crazy calculation comparing your old Volt to a Hyundai Ioniq BEV using your calculation. You can't deny this
A lithium-ion car battery has a life cycle CO2 cost of about 1.5 g CO2 / kwh / km. (1)
The Hyundai Electric has a
28 kWh battery, so the CO2 cost is ~ 1.5g CO2 / kWh * 28 kWh / km * 1 km / 0.62 mi = 67.7 g CO2 / mi. =
0.0677 kg / mi.
The
Volt has a
16 kWh battery, so the CO2 cost is ~ 1.5g CO2/kWh * 16 kWh / km * 1 km / 0.62 mi = 38.7 g CO2 / mi =
0.0387 kg / mi.
The Hyundai Electric has an MPGe of 136, or 25 kWh / 100 miles.
The Volt has an MPGe of 106, or 31 kWh / 100 miles.
For Oregon, the carbon intensity of electricity is ~ 0.11 kg / kWh. (2)
Hyundai Electric CO2 / 100 miles: 25 kWh / 100 mi * 0.11 kg / kWh + 0.0677 kg / mi * 100 mi =
9.52 kg / 100 miles.
Volt CO2 /100 miles: I'm using your typical use of 66.5% EV mode. So, the Volt will travel 66.5 miles in EV mode and 33.5 miles in hybrid mode.
EV mode CO2 cost is 31 kWh / 100 miles or 20.615 kWh / 66.5 miles * 0.11 kg CO2 / kWh =
2.26 kg CO2 / 66.5 miles
for the electricity. The life-cycle battery cost is 100 mi *0.0387 kg / mi =
3.87 kg. Then there will be 33.5 miles of
hybrid mode at 42 miles / gal. So 33.5 miles / 42 mpg = ~0.8 gallons. 1 gal = 8.9 kg CO2 (3). so 33.5 miles produces 0.8 g * 8.9 kg =
7.12 kg CO2 / 33.5 miles. Total CO2 cost of 100 miles = 2.26 kg + 3.87 kg+ 7.12 kg =
13.25 kg / 100 miles.
Please let me know what I did wrong with your calculations? It seems that the Hyundai Electric wins by a lot.
