ProLogium has begun mass production of a solid-state battery at its Giga-level facility in Taiwan, with an energy density of 381 Wh/kg.

    Looking forward to similar discoveries in the sodium ion batteries.

    These numbers are cool, and we may never see them that high with sodium, but we really need to get them to the level when we could use them in things like powerbanks and electric vehicles, and not just grid-scale storage.

    We must pivot away from lithium, it is not sustainable.

        Lithium is relatively rare, and very environmentally damaging to mine. Recycling is absolutely a must, but, as with any recycling, the recovery is not 100%. Of course, greater harm comes with large-scale applications like cars (lithium batteries are part of why electric cars are NOT eco-friendly vehicles they’re often advertised to be) and home/grid power storage, but reducing the harm where possible is essential.

        Sodium is obviously hugely abundant and we already have relatively eco-friendly salt mining for many centuries.

    What are non-solid state batteries up to, in Wh/kg? Because my car with an 82 kWh battery would need about 215+ kg to reach the same charge with a solid state battery.

      260 Wh/kg in a good modern battery.

      But the reality of SSBs needs to be verified, there already have been scams.

        That’s pretty great, for the solid state battery then. Looked it up and it seems like the battery weighs about 500 kg in my car. Very significant change down to only 215–216 kg.

          not only added range, but think of the even more fun with even better acceleration 😁

                Never had much problems with Teslas in my country. BMWs, Audis, and lately Volvos have been the wreckless (speeding) drivers.

                I myself drive a Volvo, and I think that’s why I’ve started noticing more and more Volvos, and being surprised by their frequent wrecklessness.

                  Drivers of older BMWs and Audis have had a bad reputation for being reckless drivers in my country for at least the last 30 years. Volvo, that’s a new one for me.
