Syntropic Power and UNIGRID have entered a partnership to commercialize UNIGRID’s sodium chromium oxide battery chemistry in North America.

I’ve been hearing about these for a few years now. Huge if they work out at a large scale.

    While I get that this is the narrative, people are overstating this case. High end sodium batteries have a similar energy density range to lower end lithium batteries (~150-175 wh/kg). This idea that people wouldn’t buy a battery that is cheaper, safer, and has a much longer cycle life if it weighs a bit more or only runs 80% as long between the faster charges is puzzling at best.

      They have less density than Li ion because of their honeycomb structure. They may have the same output per weight, but they have more volume.
