One such: "A 2020 study from Eindhoven University of Technology mentioned that the manufacturing emissions of batteries of new electric cars are much smaller than what was assumed in the IVL study (around 75 kg CO2/kwh) and that the lifespan of lithium batteries is also much longer than previously thought (at least 12 years with a mileage of 15000 km annually). As such, they are more ecological than gasoline-powered internal combustion cars.[58] [59] "
This doesn't even take in account recycling.
As for harmful chemicals during mining and manufacturing - it's the same for any other mining operation like gold and so on, states put in place laws that you cannot use harmful chemicals and other solutions are found. (cyanide in gold mining comes to mind)
Looking over environment aspects of production below, all the recent studies disprove what was assumed so far and your comment.
