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.
The “progress” is typical industry bullshit. See the absolute bullshit around the Donut SS battery.
Remember when Musk invented a battery with 30% better capacity? It was a 30% bigger battery.
SS batteries require manufacturing facilities with clean rooms on the order of chip fabs. You may see these in 2027, but only in expensive cars.
