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.
This too is false, great progress has been made on for instance solid state batteries.
You can’t buy anything with solid state batteries yet, and when you can, they will cost a fortune.
Uhh you know you can buy an external mag safe battery bank with a solid state battery for like 45 bucks on amazon as well as the big generator ones as well?
I agree that cost isn’t amazing. You are essentially getting about half the capacity per dollar spent to a standard battery device but also these are in fact more stable for temp swings and damage. Soo… consumer available and not a fortune just need to have justification for it.
