A surprising breakthrough could help sodium-ion batteries rival lithium—and even turn seawater into drinking water. Scientists discovered that keeping water inside a key battery material, instead of removing it as traditionally done, dramatically boosts performance. The “wet” version stores nearly twice as much charge, charges faster, and remains stable for hundreds of cycles, placing it among the top-performing sodium battery materials ever reported.
How do you recharge TNT?
I mean, we’re definitely running into a problem of how you build a battery without also building a bomb. But the entire point of TNT is rapid thermal expansion. The point of a battery is very low voltage steady release of electrical charge.
I might also note that C4 has around 6 Mwh/kg. A bit of applied chemistry can go a long way to improving energy efficiency. And that’s before you take advantage of geometry to focus pressure, via a shaped charge.
Point being, there’s a lot of clever ways to juice a lemon. We’re a long way from the end of the road on battery improvement.
