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.

    There are a bunch of lithium ion chemistries that have come to market more recently

    If you think rechargeable battery R&D from 10 years ago isn’t making it into mass produced products today, you’re just not paying attention.

    Please provide examples.

    I mean, as much as a person who doesn’t work in research and development of energy storage, or work in industries directly related to it, I personally feel I’ve kept up. The day Donut Labs announced their battery I was watching review videos about it, and I want to believe, but until I see it for purchase, I’m not going to call it a win.
