Elektrofahrzeuge übertreffen Benzinautos hinsichtlich der Umweltauswirkungen im Laufe ihrer Lebensdauer. Nach zweijähriger Nutzung führen Lithium-Ionen-Batterie-Elektrofahrzeuge (BEVs) zu einer Reduzierung der kumulierten Kohlendioxidemissionen (CO₂) im Vergleich zu Fahrzeugen mit fossilen Verbrennungsmotoren (ICE).

Funded by Albemarle Corporation, a company producing… materials for lithium batteries, among other things.
The only thing that an electric vehicle performs worse vs an ICE vehicle is tire wear. Electric cars are heavier, they accelerate faster and they have regenerative braking, so the tires wear out faster.
Admittedly thats not great for the microplastics problem, but for CO₂ emissions, energy costs, brakes and maintenance, an EV is better.
EVs cost more upfront and depending on what ice vehicle you compare it to you may or may not be ahead over the lifetime of the vehicle.
„End-of-life emissions were excluded from this study given the uncertainty regarding the role of battery repurposing, reuse, and recycling, and a detailed approach required in accounting for battery use, reuse and recycle.“
I couldn’t find a mention about heavy metals either, or pollution in general from mining the stuff required to make batteries, think there was some mention but it was quite vague. Studies like these care about CO2 too much in my opinion.
