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.
Just to clarify, because I feel that I’m being impuned in some way, my only comment was that while there has been significant development in batteries in the lab up until now this is the first commercially available battery includement since we got off lithium polymer.
The original comment I was responding to was trying to suggest that battery technology over the last decade has significantly improved but realistically all we’ve done is being come clever with the technology we already have, and that this is the first time battery technology at a commercial level has improved. After all, a lot of ICE cars are still using lead acid batteries, and the remote control for my TV uses batteries that my grandparents would have recognised.
I remember while back when lithium oxygen batteries were the new hotness and that never went anywhere.
