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.
I can’t imagine it’s doing this at a rate that will make a big impact on water supply, I suspect this is one of those things they throw in just to have a good headline.
Water supply where? In Saudi Arabia it could be revolutionary tech when combined with solar
