Considering current methods can extract 99% usable material, yeah 70% is low.

People are, indeed, liability nightmares.
They’re easily distracted, highly variable in vision acuity and intelligence, unpredictable, prone to fatigue, and their judgment is readily compromised by any number of external factors.
If cars were invented today, humans would almost certainly be banned from driving them.

The article never mentioned charge/discharge rates. Nor does it shed any light on manufacturability, which is paramount.

You nailed it! And now I know just a little bit more than I did yesterday, thanks!

Awesome! Yeah I could tell you knew what you were talking about but that last line made me go whaaa? Makes sense!

> Divide the mass by the volume and you have the volume mass of the sponge.
This calculates the sponge’s density. Mass divided by volume. Nothing further needed.
> Divide it again by the volumic mass of pure water (1000kg/m3 or 1kg/L) and you obtain its density.
This is totally useless and wrong.

I’d say wasting 30% of the lithium, cobalt, nickel, etc. in the new way isn’t exactly “environmentally friendly” either. Those wasted materials don’t just disappear.
