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.
We hear about a new battery chemistry like every week. Do most never get to commercialization?
They mostly these articles are showing new avenues for research. Most are deadends usually due to issues with production/scalability.
Sodium Ions batteries are coming to market, however the issue is that Lithium Ion are just improving faster and making it harder for Sodium Ion batteries to compete.
