- azinman2 3y agoWhat makes you say that other than price and material availability? According to Wikipedia the energy density is lower, and it also seems to have less cycles. It looks like the only thing that’s better is a hypothetical price point and the elements required.

- Sparkyte 3y agoThere is a few benefits besides cost. The battery can handle 100,000 cycles, lithium ion 10,000 cycles. Can handle being dry and over charged (lithium can not). Can also handle wider range of temperatures. Only difference is the capacity which is only about 20% smaller but the resources needed to make sodium ion is about 60% cost reduction per equal part capacity. Only if we can fix the yield problem right now.
