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.
If only they could build say…a 15W nuclear battery that can last 50 years, THAT would be something. Enough for a very low-power smartphone, one who’s CPU is clocked down so that it can’t drain energy too fast. And ruggedized as well.
gee…if only we could charge our smartphones. It’s expensive throwing them in the river when the battery drains.
