  As others have said, this is for grid-scale and not EVs, but still exceptional progress and very important for energy storage.

  I would argue that grid-scale energy storage is even more important than EV needs today.

    Grid scale batteries allow for better security by distributing storage across the network and lets us store renewable energy from peak hours.

    Cheap grid storage will be a game changer

  I wouldn’t write off EV usage too quickly. The lithium batteries in EVs right now are around 160Wh/kg. The sodium batteries coming out of production lines now are about the same, but are also substantially cheaper, safer, and built out of more abundant materials.

  Yes, if you compare them to top of the line lithium batteries coming out of assembly lines now, they don’t look as good, but those batteries aren’t in actual cars yet.

  It’s very likely that we’ll see cheap EVs running sodium batteries, and they’ll often be good enough.

    I’m all for Sodium batts in cars, but my understanding is this battery tech is a different chemical composition than other Sodium Ion batteries.

    Will be interesting if they need the same thermal management that lithium packs do. That adds a fair amount of weight to the system
