We may be able to tell with great confidence what you’re thinking or feeling but not how it feels to you. There’s a subjective, 1st person experience. Something that it’s like to be you which is different from me. I can’t tell what it’s like to be someone else, or be another animal, or if it means anything to be a rock.
I think that refers to lithium ion batteries. Some EVs use lithium iron phosphate (LiFePO4) which can still can catch fire but can be starved of oxygen. Sadly it is heavier but it is made without the immorally sourced cobalt.
