it's interesting to see the first #sodium ion batteries show up on alie, they're still more expensive than lifepo4 right now, but they already have the advantage of working in low temperatures like -40C without any differences, having a decently high discharge rate (5S pulse and 20C continuous), and being intrinsically more stable and safe than anything with lithium .. tempted to get some and do some torture testing to see if they catch on fire or whatever if you stab them like with #lithium 🤔
