Let’s hope at the same time we are building up a corresponding recycling infrastructure and products to be recycled easily. Otherwise I am afraid we are building up another trash problem.
Most of the new capacity is for large applications (cars) which means low battery type diversity, and this high reusablity due to consistency and of course high market-value. Quite a few businesses will pop up to create this solutions as the increase of batteries make it through their first life.
If you believe climate change is the biggest environmental issue, batteries could be significantly "dirtier" overall than alternatives as long as they contribute less to C02.
We have along history of doing one thing to fix another thing and causing lot of other problems.
I read it as batteries may be worth pursuing, and if so let's make them clean. That's a proposition which seems difficult to dispute.
