Smudge, EVs show a 60% reduction in CO2 emissions across the full life cycle and 80% reduction for driving in NZ.

This is some thing I read recently, but earlier in the article it suggested what is happening to ev and hybrid batteries is the are being used at off grid houses. Much lower current draw so the battery will be more usable.
Just remember lithium is only mined once then recycled many times, that's the aim at least.
. In fact I've spoken to the owner of a battery recycling company in Auckland who stated they can recycle a minimum of 95% and up to 99% of an EV battery, and that they're already set up to do so. However they've not been able to recycle any EV batteries yet, as they haven't been able to get any, in other words there are no EV batteries that need recycling yet.
