  Yes, but that is Lithium-ion. These batteries are Sodium-ion which are better for the environment and can potentially be made a lot cheaper… It’s still pretty new technology so it’s not really in any consumer products yet.

    Sodium batteries are already in electric cars many months ago

    Also you could buy individual cells on AliExpress

      Yes, but you pretty much have to do a full battery test and pen test like the great Scott video because it is really a 60/40 of getting fake sodium ion batteries from Aliexpress 😅

      Sodium batteries will not replace lithium in cars, as the density is too low.

      It means the battery weighs more but contains less power.

      For an EV, that wouldn’t work, as the heavier the car is, the more power it uses.

      With sodium you will probably half the range of the EV, which is already low.

        The newer sodium batteries are comparable to LFP batteries from a few years ago.

        probably half the range of an EV

        Many EVs have ~250 miles range. I need a quarter of that in usable winter range for my commute. If I could get an EV with 125 miles of advertised range (about half that in winter) for a third the price, I’d do it.

        It’s not going to replace my road tripping car, but it could replace my commuter, which needs very little range.

        For medium distance commuter cars and inner city travel those things dont matter and will probably be outweighed by the cost savings, safety and reliability of sodium batteries. The main issue right now with getting EVs into more peoples hands is cost.

    Economy of scale matters, so does practicality. Which one is generally lasting longer per number of charges and what’s the long term viability of both given the time they were build and the available tech at that time? I totally understand the greater availability of sodium vs lithium. However, will it last? Last time I read much about it, reliability was weak, charge capacity over time dropped drastically, and failures were high. (It has been a couple of years, so things may be changing. )

    Something new and shiney can be nifty, but past that, what is this? It seems like an expensive hood ornament that will rust in the rain. Lithium is expensive and toxic to mine, but so are all metals to some extent, and this has plenty.

    It seems like it’s buying something 25% off on a $100 thing that won’t last well. Sure, you saved $25 once, but you’re buying 3 of them in the same time frame.

      Nah. Time to reread, sodium is absolutely a viable tech now.

      • Piemanding@sh.itjust.works ⁨2⁩ ⁨days⁩ ago

        Yes. Last I saw they lasted for more charges and had similar capacity to lithium. It’s been invested into so much because it is viable.

    There are some electric vehicles so far, which is promising.
