I’ve always been concerned with the sustainability of lithium batteries, which are, dirty to manufacture. The precious deep earth metals needed for them are not sustainable either. It’s the biggest hesitation I have getting an electric car. I’m hoping that graphene will change how we make everything, and with it’s properties being 100% carbon which is abundant, cheap, and sustainable I can see technology reaching a new age. I know our understanding of how it behaves in rigorous testing is early but you can’t deny it’s potebtial on nearly all aspects on society. Thoughts?
