Found this, not heard of aluminium air batteries before. Recharging batteries is way more convenient than swapping out an aluminium cathode but this technology is sure to have its place.

I agree with you Snowy.

Also want to correct something she said in the video:

Quote"98% of Lithium-ion batteries end up in land fill"

That statement is incorrect.
Every single car manufacturer has an end-of-life reusing/recycling scheme.  

Found this about hot liquid aluminium batteries. Not for every application but interesting tech.
