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.
But you can’t imagine it doing a lot more?
I don’t think batteries will soak up that much salt for their use. And I’d imagine they saturate over time. It’s very different than something built specifically for deslination.
