Wait a minute, 33% the volume, and 2.5 the weight? You're saying the weight density of this battery 7.5 times higher than regular batteries!?

7.5 times heavier than water, heavy stuff indeed…

That's about right for solids overall. You'll easily find things 5 to 8 times heavier than water.

Nope. The 2.5 figure is kilos per watt-hour. Not litres per watt-hour.
